Numerous menu issues

Hi, having a few miscellaneous problems as the title states.

Can’t really find anything with Google and I verified the cache twice.

For the multiplayer tab… well it’s self explanatory, can’t change my spray either.

The icon on the taskbar is set to Half-Life 2’s, as opposed to Garry’s Mod.

and Anti-Aliasing is limited to 8x as opposed to 16x, which I was able to enable before Garry’s Mod 13. Anyone have any ideas?

Well, the reason for your multiplayer menu is the games you have mounted. From the current layout of your multiplayer menu, you have Half Life 2 and Counter Strike: Source mounted. If you have Half Life 2 Deathmatch, try mounting that as well. For some reason the games you have mounted changes the multiplayer tab.
