cleaning gmod

vistta wont let me rename gmod it says you do not have permission and im using my admin account

Close Steam, and try again.
If that doesn’t work, restart your computer without starting Steam, and then delete the folder.

also when gmod is loding a map it takes forever

Too many addons. And probably not exported either.

did it and still not fixed

If you remove all your addons and a map still takes a long time to load, it could be just your computer, make sure you have no other programs running in the background.

its ok its fixed
