sorry....i think maybe i didn't explain well...and seems everyday i find out as bit more about it.
heres the scoop.
I bought a MSI Ti4200 video card (awesome btw) and it included GR....when i tried to update it i had all kinds of probs. so i gave up....then they have come out with GR GOLD which included BOTH exp and the game....thought it seems like a great deal so i BOUGHT it. I uninstalled (correctly) the MSI version and installed the new GR gold. when i tried to start the game it now asks for the cd to be in the drive (only drive...correctly lettered) over and over and over.
