I just purchased a Gamestop Power Up Card. When signing up online, it asked me a questionaire and I keep getting an error where it says that I may not have answered all questions, or all questions correctly. I have answered all questions, but it's asking for my gamertag, which I know, but also my online id and username. Neither of the latter two I know what they are asking for. Could someone please explain to me what they are asking for and where I can find this? Thanks!
