after patching when i tryed to log i got a message 'game client or game guard has been altered' after few sec game guard closes connection = cant play :/ i deleted files in gg folder so it redownloaded during start (didnt help) i reinstaled game (didnt help) today i was bored so even formated computer (pc was slow so kinnda needed it anyways) instaled client on fresh system but same message pops up
i wont lie to you i dont know much about computers so if anyone could help it would be great
