I keep having a problem with GMOD. I installed GMOD after downloading it from steam, and I downloaded som maps and shit, the game worked fine then, but later, I tried making custom backgrounds, I made one, it worked well, so did the rest of the game, but after that I tried to add music and a different background, then this came up:
SteamStartup() failed: SteamStartup(0xf,0x0012E59C) failed witch error 1:
Failed to make master pipe connection lock
what the heck does it mean, i tried deleting the music, but I still got the same message.
please help me out here.
