EP1 engine games won't run

I’ve got Windows 7, I can play every game except EP1 engine games.
I get this error: Platform error: Module failed to initialize
Or I can’t see the buttons

This is a garry’s mod forum. Go check out steam support they normally haev a fix for stuff like that.

Try updating graphics drivers

I found the bug, I needed to disable community chat in-game and then enable it.
