So I recently installed the step through MO step by step very carefully. Hell took so many hours. Also I cleaned the "dirty" files with  BOSS and TES5dit program, seems pretty clean now. However, whenever I enable .esp files in MO, I get CTD when it's in loading screen.Â
Also, I haven't figured out what .esp files are causing them, but so far I know there is more than one, many of them which causes CTD, and now I am absolutely helpess.
This does not tell much, but I hope you guys here will have some answers or instructions what should I do, because I ran out of ideas how to get this thing to work.
