Hi: I am having the same problem. Although I received an e-mail telling me that my old username is reserved for me, when I attempt to use it on the new format, I get a notice saying: "Username does not exist".
Is it possible to get an e-mail where I can direct my question to the administrator? If not, can someone respond to me on this thread? I would really like to be able to enjoy my "free subscription" as promised in my e-mail.
Any help that anyone can give me would be much appreciated.
