XHI-740-61867. What's more annoying is I got an e-mail tonight saying that Stardock has not had a response back from me in 72 hours. I was never asked to respond! I replied back as the e-mail said it would consider the issue resolved if I don't respond.
My husband was able to find a Key on the Impulse account. Why is this key different than the Gamestop one? The impulse one worked. My only concern now is updates. The instructions for installation help on the website said to use the GameStop key and had step-by-step instructions on how to do this.
