I did not get any error notifications or messages after registering. Everything worked normally and Avast! said I should receive my new license key within 24 hrs, which did not happen after my initial re-registration 3 nights ago. However, I just tried registering again with a different e-mail address and was successful in obtaining a new license key. I do not know if using a different e-mail address had any impact on getting a new key as opposed to Avast! resending my old key as I mentioned earlier.
