Source SDK: Episode 1 Problem

I don’t know who else is having this problem but whenever I run Hammer with the Half-Life 2 Episode 1 setting the quadrants show up as black with a white line or so. I have the Engine Version set on 2006 and iv tried multiple things to fix it. Resetting Game Configuration, Edit Game Configuration, Re-Downloading Source SDK, Re-Downloading Episode 1, and messing with the games settings in Hammer. Not sure what to do. Also as a side note, my Current game options for Half-Life 2 Deathmatch and Counter Strike are in a weird situation. Whenever i try to select them they automatically select just regular Half-Life 2 instead.

Thank you for anyone's help.
