ok well still having the problem, and i tried a 3rd computer, same thing. this time when i uninstalled after the first error it errored like 5 times but then continued to uninstall. someone gave me a direction on windows vista to right click the icon and select run as administrator, so im going to try that tonight. if it doesnt get resolved in the next fews days i am more than likely going to return it and wait for the ps3 version to come out.
