I managed to get the files from a link in another post, but now that I think about it...the reference files get wiped out with every update, so it's kind of futile constantly download new reference file with every new update.

They were the newest set of reference files (entrenchment 1.041), and I still have no idea why they weren't working. Luckily, I found a way to sidestep the issue by converting my own files into txt form. Thanks for trying to help, though.
I'm practically new to modding Sins, so it may be ineptitude causing the problem, but I can't seem to alter the game at all using the reference files. Even if I just copy-paste game info without changing anything, the game crashed when I enable the mod. I've made sure I'm using the latest reference files, but they still don't work. I can, however, use copied files from the original Sins of a Solar Empire GameInfo folder, but these can't be modified...only deleted. Is ther
