I am writing it exactly as the e-mail requested. With capitals at the start of both the first and last names. I have even tried all capitals, and all lower case. It simply says 'No such Handle'. My guess is I wasn't properly added to the database.
I don't want to re-register, because a) it takes ages, and b) I will probably get banned.
Has this happened to anyone else before? If so, what did you do??? Thanks.
