things missing

idk what happened i just added a couple of things to add on and the beginning buttons disappeared and i don’t know how to get them back

Reinstall Gmod. All the addons will still be there if you reinstall.

idk how to reinstall
i forget where to go on steam to reinstall it

Games library.

Aren’t you that asshat who killed me when we were both traitors on Trouble in Terrorist Town?
Anyway, right click on Gmod in your steam games library, and click on “Delete Local Content”
EDIT: Wait this guy’s GMOD is pirated he owns no games

Yup. He registered yesterday.
