Unable to select HL2: EP2 as a game plus other problems

So I was going to start working on this map I had tons of ideas for, but when I attempt to select EP2 as a option in source 2007 it snaps back to portal and I cannot select ep2 at all. And then games like CS:S, HL2, and EP1 are not in Source 2009. Is there any way to fix this?

Use the reset game configurations option in the SDK. Then restart the SDK. Problem solved.

I tried that, didn’t work.

Run ep2 again.
