Hexing Trouble!

So i followed a tutorial about hexing cuz its my first time.I did everything it said and when i go in Gmod and try to spawn my model Gmod crashes.I dont know whats the problem i went trough
everything twise and everytime it crashes.What could be the problem ?

Send me the model and materials stuff and I’ll hex it for yeh.
