Hmmmm.... havent seen that one CanadaMan, i got the resize tool to work. I did a copy over on the mscomctl.ocx file that i got from the ms website. That and i re-downloaded the resize tool also, probably wasnt the tool, but it worked fine after i installed and re-started the computer.
Happy Days!!! Haha, anyway, it worked and everything is fine, the hardpoints fire for me, from the same points, how big did you re-make the mesh? I notice that if i take them fairly large the textures all go red, or blue. Not very cool, but i was able to get that fixed by removing the secular textures for the models. Not the best fix of course, since it leaves out the beautiful sheen on the models, but it does take away the reddish and blueish glare. 
Perhaps some of the more experienced modders could help you with the hardpoint stuff, but as i re-call, you have more experience than most of us here,
So the devs may be the only place to turn for an answer. Sorry, im just a little file tweaker mostly that has been getting into the meshes and textures and im in deep water over my head most of the time, and making guesses to see if i can get things to work. Haha, anyway, take care and hope you get an answer that helps.
Sincerely,
