Glad you got it worked out! As for installing the EE5.0 mod, I'd hold off on that since the latest RFB comes with PE already integrated. Adding a different environment mod may cause problems.
As for your problems with Nvidia, that's unfortunate it had to be that way. Sounds pretty unprofessional on their part if you ask me. I've never used their products, only because my first PC came with an ATI card installed (8mb ram: Christ! How long ago was that!

) and I never, to this day had any problems with any of their products or drivers. I'm very satisfied with ATI
