Hello! I was recently told that, because hammer kept crashing during compiling and making me lose work, I should use VBCT. That was working all day yesterday, however, when I go to compile my map, I get an error now. -------------- Start Compile BSP ---------------- VBSP Started, Please Wait! VBSP: c:\program files\steam\steamapps\****\sourcesdk\bin\orangebox\bin\vbsp.exe -game "c:\program files\steam\steamapps\****\team fortress 2\tf" "C:\Documents and Settings\NAME\Desktop\FF2_SpaceBattle\FF2_SpaceBattle" SteamStartup() failed: SteamStartup(0xf,0x0012EB84) failed with error 1: failed to take master pipe connection lock Compile Complete for this module.

So yeah...I've tried verifying TF2 and the Source SDK files, still didn't work. EDIT: Censored by me because I felt like it.
