It was working perfectly fine with almost 100 mods
Now it doesn't.
tried EVERY SINGLE THING IN THIS THREAD SO FAR, multiple times, to no avail.
Can't be my PC, since it ran before. Can't be mods, since I didn't get any new ones. Can't be .dlls, because I tried both installing from links and verifying cache. Can't be version, because there weren't any updates.
Going to reinstall, wish me luck...

EDIT: Reinstalled it AGAIN. Rebooted my computer. NOW it goes up to initializing facegen, the wndows pop up, and THEN it stops working

EDIT2: Followed step one of this and it's workin' so far. If not for you, continue on to step 2;

"1. right click creation kit.exe select troubleshoot compatibility, tinker with that until you get to a window that tells you the creation kit is incapable. there should be a fix option, or it automatically fixes it, once again sorry

2. here's somethings else i did while trying to fix this. open creation\properties\compatibility check off "run this program in compatibility mode for:" i selected windows 95 then tried opening the creation kit, but, nothing even popped up. so i changed the compatibility back to run for windows 7, and it opened right up. no more unknown reasons for it not working and crashing anymore!!!!"
