while playing on these games:
Team Fortress 2
Counter-Strike: Soucre
Half-Life 2: Deathmatch
Garry's Mod
I get disconnected from a server (after about 5 minutes) with an error saying something like "No connection could be made to the VAC servers blah blah blah)
i've already tried:
restarting steam
reinstalling steam
rebooting my computer
opening ports on my router
removing my firewall
can anyone help me?
