Quote from NihiLIf everything including crowbar fails then I can really only think of your studiomdl.exe being corrupt or maybe it just doesn't run on your computer at all or something, sorry!
Okay I'll get this tested by a friend
.
EDIT: Just to ask though, where does crowbar take the model file from (the smd) ? As far as I can see, it is only the qc-file it uses and maybe my error has to do with that ?
