Please help me out!

calm down, just drag and drop both files into the garrysmod/garrysmod folder, no where else. and if it asks to overwrite just say yes to all

This file has no spawn menu options… To spawn the ragdoll you need to go to the browse tab on the Spawn Menu and open All > Playermodels

Thanks man! helped me a lot!
You, sir, are awesome
