I had a similar problem and tryed to register again. Afer this I received an email rejecting my seccond account. Last sunday I sended a mail to the multiaccount support as said in the mail I received last and I still didn't have any answer. Shouldn't I send this mail? Should I do anything else or just wait? My second handle (the one with the correct email) was Atrok Griel.
Please open a new thread for your problem rather than posting in someone else's.
You will need to include the first handle you used to register, the old e-mail address, and the correct e-mail address so someone can fix it for you. Registering a second account would just get you declined for trying to create an illegal multi.
