In case someone else has crashing problems like me, the best way i found without crashes is :
- Launch game, wait till main menu pops up
- Activate trainer and activate all cheats you want
- Load save
What do you do if the game crashed, and will not load anymore, even after re-install? Something happened with it and WeMod that my game didn't like, so it crashed,and now my PC will not let it play. I checked everything for errors, and my PC is perfectly fine, and plays all of my other games perfectly. It's only this game that is broken now, and WeMod says it can't load it anymore, and also it will not load normally.
EDIT: Okay, so re-installing the game fixed it, but then WeMod broke it again, so now on my fourth install. WeMod seems to rewrite some of the files, making them corrupted. After a fresh install it works again, untill I tried WeMod again. I won't be using WeMod anymore, as it seems to damage my game every time.
