First of all : good time of day , everyone.
Recently ( after that whole game destroying source engine update) I get crashed with this [url]http://dumps.garrysmod.com/?view=3393444637&refresh=11[/url] error.
I have uninstalled garrysmod , and I have tried to remove the addons.
it still doesnt help.
I have Portal 2 to play now , but could anyone please help me to fix my favourite game?
Thanks for the incoming help
