Unable to upload using workshopper

So I am trying to upload a mod for GMod 13, YES I’M USING THE LATEST VERSION OF WORKSHOPPER.

When i click upload. it shows UPLOADING TO STEAM WORKS and the progress bar. When its done it goes to my uploaded addons list. But the new addon isn’t there. Also it doesn’t take me to the workshop page, and when i check my uploaded files, Its not there… WHY???
