how do you guys compile models?

[o_stino]

i'm trying again to compile the doors of badlands to fix the collision problems, but it seems that i cant compile it anymore, with StudioCompiler.exe (cannonfodder) i get 3 files: .mdl .phy and .vvd
if i try to use
studiomdl (valve) i get an error:
ERROR: 'EXCEPTION_ACCESS_VIOLATION' (assert: 1)
and it outputs an mdl file that is way to small.
