I needed to re-download gmod so i had to remove it.
I pressed delete local content and I went into my steam folder>(username)> etc. and saw it was still there with alot of files inside it.
What do I have to do?
Ok, nevermind. I figured out how to do it right.
(C:// programfiles / steam / steamapps / username / gmod)
Why is it when you re-install gmod it starts automatically at 94%?
