I try to open TF2 or Gmod and it just brings up the "Preparing to launch" window and never does anything. I can run games that use launchers like Forsaken world, but I don't like that game. Anyway is anyone else having this problem? I've waited for at least 5 minutes to see if TF2 would eventually open but it never did.
P.S. I've signed up for the Steam forum but can't post yet, so I posted here cause I didn't want to wait.
