Couple more ideas in addition to what mnb1985 suggested:
- Try running the game on Steam
- Try going back to a previous restore point on Windows
A complete Windows reinstall is rather extreme, unless you're having other problems with other apps.
Thanks bud, Steam is same and Since I don't use windows for anything else- I really didn't have anything to lose but time on re-install.
WGT is looking into it, Hopefully will figure it out- I still haven't tried a different PC but my gut says this is something on their end. Still shocked/surprised that I haven't heard of anyone else with this problem.
