İ can mounte Garry mod?

Im not sure if its just me but i cant join servers. it says the game is an old version. Please fix this

Does this have single player mode? coz i read multi only in steam

PLEASE REUPLOAD!

Thanks for the download, it works well. Just wondering, why does the game crash every time I click customize? is there any way this can be fixed? THanks.

Thank you very much. Best website ever
