When I load singleplayer on Garry's Mod, the game just crashes as it finishes loading, regardless the map or the gamemode. I don't know what to do; any ideas? Thanks!
The best thing to try first with games on steam is to check that your local files for the game are not corrupt. Right click on them in your library, Click properties, click on the local files tab and then click "Verify Integrity of Game Cache". That pretty much sorts all of my issues with Steam games.
