StudioMDL Issues

I’ve been attempting to compile a .QC file through the studiomdl.exe in my Orange Box Engine bin folder, but it keeps failing to actually do anything. The window pops up, flashes a line of yellow text mentioning something along the lines of ‘Failed to load pflibb.dll’ and instantly closes.

Anybody else have this problem?

Specifically, you need to run with -nop4 to disable the Perforce integration system Valve use.

Okay, well it actually tries now, but it is saying it can’t find TF2’s gameinfo.txt, but it is in the TF folder. Is this because I haven’t set it up right?
