Im trying to join a server in GMOD but i get that error, and it happens in all of my games
Restart / system restore / game re-install didn't work?
Ive got alot of mods for Gmod and i don't want to go reinstall them all, i guess i could make a dump of them on a flash drive.
Thats what happens also when you join a server that isn't updated (at least as far as TF2- clan mates be mad at me for not updating server till like 10 min a go cuz i was gone) .
