Hi,
Before I answer your question I would give you a strong advice when using the Internet i geneneral. Avoid putting up information anywhere. That includes e-mail, passwords, and serial-keys, etc. Furthermore, I recommend that you edit your post and remove the serial-key from it.
Now on to your question. This is something that has happended of lately, as I've understood it. Therefore, there is a thread on this forum discussing the problem. Furthermore, this thread has been marked as solved so I strongly recommend you to check on the thread to get the answer.
Good luck,
Lonori
