The winners for summer MOTS are D-ead7Dog, toonanimals317, and Telluric! Congratulations!
I deleted every file that has something to do with FH and installed it again. Still nothing but I think the laptop is the problem. Because I also cant play another game that needs the same grafic quality like FH. Ill check my grafic card. I bet there went something wrong. But thank you all for the help.
