I don't understand why this is happening. I installed HL2 and HL2:E2 as well as SDK base 2006,2007, and the SDK source kit. I then install the game as directed (via .exe), and the game crashes right after the we create stuff logo. This is pretty frustrating and I have no idea why this is happening. It was loading earlier today, but I was getting the purple textures and error boxes, so I reinstalled everything and now I'm getting this error. Any help would be greatly appreciated. Thank you all very much. I am starting a horror lets play and creepypasta reading channel and this was going to be my first lets play. I'd really, REALLY like to get started on this as soon as possible.
