My fix was to reinstall NVidia driver, clean install. Once done right click C (system) drive -> Properties -> Disk clean up-> Clean system files. select all and ok it.
DONE!
After working several months with Microsoft\Studio10, I got nowhere with their support. I sent them many files over the months with no resolve.
I fixed it myself accidentially.
IF YOU HAVE A USB DEVICE PLUGGED IN AS READYBOOST CACHE, DISBALE IT AND REMOVE IT.
In my case this fixed my issue and now the game properly loads. Your welcome Microsoft/Studio10 for the fix!
