Game crash / Windows freeze when entering lobby or loading screen

[ShaZe]

Does this happen to anybody? My system just completly froze with a looping sound, windows 98 style when joining a lobby. I usually don't have problems but every once in a while, something crash my USF4 or the system.

I feel like some users are trying to use weird mods online or maybe the game really is broken. Iv never had these issues before.
