I'm going to assume you got the model from a trophy because of the bone theory,
first step:
Export your .mdl0 then delete everything in the bress that isnt a texture go to the top of the bress and hit export. (don't hit save just close it)
Next Replace the Texture[whatever] with the bres that you exported. and replace the model with your mdl0.
should be working by this point, have fun importing animations
