Radbox hl2.exe crash.

Hey, I’ve been trying to fix this for a week or so now with no luck. So I recently made the first map for Radiation Sandbox but, I can’t load radbox on any map, singleplayer or otherwise. I couldn’t before I made TheLonelyRoad either. I just deleted my whole gmod folder and reinstalled but I still crashed with hl2.exe error. So now I’m completely out of ideas, can anyone help?

  • RAM 3gb
  • Graphics Card 2x Nvidia GeForce 8800s
  • Operating System Windows vista home edition

Addons: Just Radbox 1.15

Bump, sorry. Really need this.
