Just wanted to say that after a few reinstalls the patch finally worked, and I was able to follow the steps right up through all the DLC installs. Everything works now, although it seems I still have crashes, in particular the game always crashes in OA right after the pulse field goes down and you assault the main base. It seems this game is just meant to challenge and frustrate me :(. I have no mods besides all the patches and stuff, so I dont quite get it. Maybe because I run on 64 bit? Anyway, thanks for youre good guide, Im sure it would fully work for me if I wasn't cursed.
