Quoting Horemvore: 0.3f is a patch you install over the main mod

Did that. There are two versions of 0.3f, lets call them one and two to avoid confusion. Two contains the federation wonders.

When I copy the files from 0.3f version two over the files from 0.3f version one I get the error I mentioned. I get to the main menu but no Star Trek races show up. If I overwrite those files, and only those files, with the originals from 0.3f version one I get the full mod once again including access to my last saved game. That tells me it is the new version two files that have an issue

On another note, here is something I have been playing with for the Klingon's:

https://1drv.ms/u/s!AokCVy_b1r7j4CjKSqx-O8OQNHK9

I modified the weapons names and descriptions but did not touch effects or strength. I also removed any mention of slavery from the tree, Klingons are described as brutal in combat and unrelenting but honorable. They would not employ slaves, not fun to be working under them but you would be treated with honor. The mention of slavery for them would be a real turn off to die hard trekkies which is a large market segment. Some of the other races on the other hand ...

I will continue tinkering with the tree as I go without touching any values so as not to upset the current balance. Your call on what you want to use if anything. Just trying to make it a bit more compliant with Trek canon.

I toyed with the idea of using actual Klingon names, there is a full language dictionary available, but that just seems a bit too geeky LOL And no, I don't go around dressed up as a character LOL

Like 90% of the changes, just not what you did to the cannon tech names, does not fit. Klingons have Disruptor cannons, not Anti Proton (Uniques for every race just not done them yet), Kinetic(No Longer exists other than damage type, and not very Star trek canon like), Tetryon (Tholians), Polaron (Breen/Dominion) or Singularity. Did however add it to 0.3f, before I saw the cannons.

Yea, I struggled with the cannons. Was trying to avoid using the same term, Disruptor which is strongly associated with beams and ended up recycling already existing techs. Most Star trek sites and encyclopedia are very sparse on Klingon kinetics, concentrate more on Disruptor beams and torpedoes having "Disruptor cannons" as the one weapon incrementing with Mk 1, Mk 2 etc ...

Ug I just noticed the Torpedoes too. This is from my Notes:

Missiles

Stinger - Spatial Torpedo
Harpoon - Photonic Torpedo
Photonic Warheads - Photon Torpedo
Photon Torpedo - Quantum Torpedo
Nightmare Torpedoes - Polaron Torpedo (Klingon & Dominion)
                    - Gravametric Torpedo (Borg)
                    - Plasma Torpedo (Romulan & Cardassian)
                    - Transphasic Torpedo (Federation, Fernegi & Breen)
                    - Thermonic Torpedo (Tholian)
Beams

Polaron Beams - Dominion & Breen
Distruptor Beams - Klingon & Romulan
Tetryon Beams - Tholian
Phaser Beams - Federation, Cardassian & Ferengi
Adaptable Disruptor Beams - Borg

Kinetic

Plasma Cannons - Romulan
Phased Polaron Cannons - Dominion & Breen
Tetryon Cannons - Tholian
Disruptor Cannons - Klingon
Phaser Cannons - Federation, Cardassian and Ferengi
Cutting Beam - Borg

There is a method to my madness, honest.

new version uploaded following your template more closely.

Played with the cannons while keeping the disruptor name and idea. replaced the torpedoes with your names, edited the descriptions. 

By the way, found out that polaron is a real thing based on a Bose-Einstein condensate particle called polariton. Cool!

Should be a different file showing various flavours of 'Disruptor cannons" as well as the missile names you use. Not sure what happened there, repackaged and reposted to:

https://1drv.ms/u/s!AokCVy_b1r7j4Csty2duHQDDm-o7

I am modifying the strings that the KlingonX_Name" points to in the ST_KlingonTechDefsText file. No changes made to the tech file all made in the text one. Learned that the hard way.

Here is an updated Klingon tree. 

https://1drv.ms/f/s!AokCVy_b1r7jal0Tb6U966psMYo

I removed all references to slavery replaced it with scientist or worker references

I removed all references to other races as "food species", replaced the term with "enemy", "other races" or "lesser races" depending on context. I still need to go thru every description and Klingonize them to remove the Drengin flavor that remains but at least now it should not be as jarring to read some of these description in the context of playing Klingons. They certainly do not eat their foes, although drinking blood wine in their skulls might be feasible Added some Kilngon terms in a few places.

There is an updated Star Trek - Star Names 1.81 mod on the OP.

So far so good, no issues with new version of 0.3f. Playing Federation on immense with everything common. The new wonders are available and are being built Interesting way to soak up some of that early game Elerium and Prometheon, especially the elerium as it now makes the decision to build the Elerium defense shields strategic, do I build those or wait and accumulate to build the Starfleet wonders? Good choice!

I like the Federation tree by the way, it feels right!! 

They should be 500 from the start. Make sure you are not using any other mods that modify the Starbase files.

What faction are you playing? Not that this should make a difference, but I can check none the less.

Wonders seem to work but one question. What is the "Commander" that the Starfleet improvement is supposed to give. Pretty sure I saw the weapons increase but not sure where to look for to confirm I get this one.

Take a look at the entertainment section of the Governance branch in this tree.

Is that what you had in mind for some Klingon names?

I think I figured out what happened....  I changed one of the Federation faction's abilities to Vigilant.  From what I can tell, when a race with the Vigilant ability constructs a starbase, that starbase starts out with 200 HP.  This occurs even if the StarbaseDefs.xml file specifies 500 HP.  I tested this by deleting the Federation's vigilant ability, and then I could build 500 HP starbases.  That is strange; possibly a hardcoded bug? 

Anyway, maybe it's not such a bad thing.  The Vigilant ability is overpowered IMHO so taking a big cut to starbases hit points might be good for balance. 

Updated 4/8/16 - See Change Log. Will not be working much on the mod for the next 2 weeks, shifted over to 6-6 Night Shift.
