Garry's Mod 13

[mazejaker]

I downloaded Gmod 13 yesterday and had no problems with it. I was messing around with the new features and stuff, like everyone does with Gmod. Today however, I broke it... Me and my friend were going to play some map we found, I started a server and he joined, I was looking through the item libraries for some Left4Dead2 stuff, and I clicked a folder to look at the items, and it crashed. I was fine with this, even though it meant I had to restart the server, I didn't really care. However, now everytime I load the game, it gets past one loading screen, goes onto a blue screen and then 'hl2.exe has stopped responding'... EVERYTIME. I validated game cahce, still happens, I deleted and reinstalled it, still happens. What the hell??? What is wrong with it, and what can I do to fix it?
