Mdldecompiler Crashes with Animations

The mdldecompiler keeps crashing every time I try to decompile any animations.mdl. I’m using hooch’s decompiler and it is set up in the right files (sourcesdk\bin\ep1\bin). It’s also hexed from IDST1 to IDST, and even with all that, it still crashes before it can decompile the animations. It does decompile correctly when it comes to regular models. I’ve checked all over the internet with google and no one has the exact problem I’m having. Please any help would be greatly appreciated.
