So, recently I got HL2 working. And I wanted to try and make some maps for it, and so I made a config in Hammer for it, and... Hammer didn't like it(for some odd reason). And now all the little screens are completly black(they still work though). So now I don't know what to do, I tried re-configuring, deleting user info and nothing helped.
Maybe somebody has also encountered this bug, and will help me.
