Compiler help

I can not get GUI Studiomdl or studiomdl to work at all. For Studiomdl, it simply crashes every time I try to set the SDK tools path; and for GUI Studiomdl it gives me the Steam master pipe connection lock error. Are there any programs out there, and if not, is there any way to fix these problems? Could someone please help?
