The third installation is where it will get sticky, but then again it's not that big of a deal. You call a Microsoft rep, and tell him/her your reason for putting the key in again, and they will give you a confirmation code and it will work fine. I've done this before, told the guy the first installation had an error, the second was for my computer, and the third was a reinstallation because I had to format my computer.
