I had the same problem back in november I contacted the webmaster (Darius) and he corrected the situation in a fast and professional manor.
Below is the email I recieved from him
Good Day Mr. *****:
I apologize for this not working for you as it should. It turns out that your login account was disconnect or otherwise not associated with a valid customer account. Sometime during our startup of this new site we had some customers have their accounts become disconnected like this.
I have reconnected the customer account ****** to the login for your account – that is, the login name of *********.com You should be able to login now with this and shop and checkout fine without getting that error.
Please let me know if there are any further difficulties at all.
I appreciate your business and your patience to keep trying! Thank you.
