When I try to upgrade to the Grand Prix version from my Petrol Head one, via my iPhone5, I get a message saying that I bought the original with a different ID ... from when Apple changed my regular email address to their .me.com address ... without asking or telling me. So for a short while I was buying with the .me.com address before I realized what had happened.
Is there anyway to rectify this on "your" end. Apple says there is nothing they can do.
Thanks ....
