DivineWrath: You may have hit the nail on the head. When I DLed the Gamestop app, I tried to enter the same username/pw combination that I have with Stardock. However, that did not work (it said that account did not exist). So I created an account with Gamestop with the same username (or email address) as my stardock account. That might have been my blunder.
I have changed my username/pw combo with stardock, and that my current combination is different than it was 5 years ago. So that might be why the Gamestop app did not recognize my current username. I wonder if this means I have to guess at my previous username...
Kryo: Thank you for your response. I re-read my original post, and I hope that it did not come across as disrespectful. I appreciate stardock as a company, and they have always treated their customers well. As you suggested, I will try to remember...my previous account with Gamestop/impulse. I am not sure that I can---it's been around 4 years since I last interacted with the program.
Thank you for help! Both of you!
Warmly,
Wyatt
