Here's an idea. Take the game back to the store and tell them something is wrong with the CD and it will not install and ask for another one. Most of the time they will give you the replacement title still packaged. Take your new unopened software package to a different store (Wal-Mart would be good) and tell them you received it as a gift. You will receive a store GIFT CARD to use in that store.
Oh ya, make sure you have a copy of the CD image before you do this. Just an idea
