Source SDK Is Broken


Website Zealot
So today I wanted to map for Source 2007 (dont ask) so I tried to boot up HL2:EP 2 in Hammer. I could not see anything in the 2d views, after asking some mod devs, they said refresh my SDK configs. This didn't work. So I searched the internet, they suggested a full reinstall of SDK. I did that, deleted the SDK folder and everything. Then reinstalled. I got this.

After I explained this to the mod devs, they asked if I ran each game once. Did that, and nothing happened. Ideas?
