Another Garrys Mod error.

Ok so today I treid to play Garrys Mod and it worked but then It crashed. Then later I tired to play Garrys Mod again and I got this error “SteamStartup() failed: SteamStartup(0xf,0x0042E01C) failed with error 1: failed to take master pipe connection lock”. Could anyone tell me whats wrong becuase it just wont startup and my L.A Noire is overheating my PS3 so I cannot play that instead of Garrys Mod. :confused:

Update 22:37: Resolved requesting lock…

Restart steam?

I will try that I’ll edit this if it works/fails.
