@Ewu: Thanks so much for your prompt response :O
Unfortunately, I'm in somewhat of a strange predicament. One artist registered with part of her full name for her pre-reg and I registered her with her full name for the AA reg, so I know that's causing one error. The other person I'm having issues with registered with a different email for her Fanime pre-reg than the email I registered her with for the AA reg. I have both of their correct badge numbers but I can't change any of their previous Fanime pre-reg information so I still get the "registration not found error" for both of them. Basically, I can't find a way to change anything that would make them match.
Is there anything else I can do? I did send an email already to artistalleyATfanimeDOTcom, which has more detailed information.
