But if you're desperate, perhaps read these:

1) Decompiling a model

2) Re-sizing it

3) Re-compiling it

If you do those 3 you can rescale any model you want.

So to get it working, either someone has luck getting it without damaged joints or you will have to reassign all joints and redo the animations.

If someone wants to find the error or invest the work, I attached the source files.

I think you linked to a propper tutorial for the recompile. Propper is for making brushes Into models.

Once you got the .qc file (altogether with the .SMD files) of whatever model (doesn't really matter if it comes from Propper or exported from a modelling program) you need to recompile it, and there in the Propper tutorial I explained how to do it by using the GUIStudioMDL... You could always take the "recompiling" part from that guide if you need to recompile any model... it's valid
