Bought advanced....money being wasted as Q menu doesn't work in BB...works on other servers and single player...WTF??? :-\
Only advice I can give is to delete the garrysmod folder from your steamapps/username directory and let steam extract the content again. This does mean you'll have to download any addons and such that you don't back up however.
you can just change the name of your current gmod folder and them you can copy all the addons and stuff.
Done all of the above and re-installed Gmod...steam id was correct as i have toolgun and physgun and class but no q menu?????? :-\
