I called 800-4MY-XBOX today. The guy at first said there was no way to recover it. Then he said if I reconnected to Live, it would recognize that I "bought" it and could re-download it.
I then explained that Hexic is a free game supplied on the hard drive. Then I explained to him what I read on this forum about the download code. Then he finally got the picture and I held off and on for about 20 minutes.
He then verified my phone number several times and finally transferred me to a supervisor named Royal. Royal stated that they would call me back in 48-72 hours with the code. Plus he gave me a ticket number to reference if I need to call back.
