SwitchKill

After more hours of troubleshooting i came to the conclusion that somehow the culprit was FCO so i decided to just remove the mod. Thank you all for your help!

Game loads up to the point when the main menu should appear but it does not. Meanwhile in the background i have the error window pop up since the beginning. I tried to use FNVEdit but it did not return any errors...
