I downloaded from the mediafire link and decompiled "excalibur.mdl" using Crowbar 0.24 (the latest public release). It created a QC file, 4 mesh SMD files, and a physics mesh SMD file. Looking at them in Blender or recompiling into an L4D2 model showed a humanoid model.

I can only guess that maybe you used an older version of Crowbar that had trouble with the model, or that you are misinterpreting where the files are.

If you still have trouble, post screenshots of the Decompiler tab and the Windows folder (with the full path somehow shown) where you expect to find the files.

I'll check it out. Thanks for the report.

:)
