I am in some trouble.. A few hours ago everything was still ok with my game. Now I started a new session, recovered the files of the CS extender which I had deleted from the recycle bin and after editing a mod I attempted to launch the game from there. But it crashed during the loading screen. I played around with load order a bit and sometimes I could get it to work if I left out certain mods. But there was no reason why it should be related to any of the mods which were all fine before, so I copied in my save copy of the ini file. Now the game started properly again, but all saves crashed when I tried to load them, with or without any mods loaded. What can have happened?

I do not know what exactly went wrong, but surely this had something to do with it?

How exactly did you "recover" the files?
