I tried to find help in the forum and I tried reinstalling / starting as admin / chaning quality etc. So according to some older posts I guess it's gotta be some other process / programm stopping it? League actually doesn't even appear in the "detected games" while some other games of mine do.
Maybe some of you guys had the same problem and found a way to solve it.
Thanks in advance!
