Registration Problems

Hi I received a Envivo controller at Christmas, did the installation as directed (including Cross DJ LE) Registered for an account with MixVibes and input my registration number as required. However when I start the software (v2.5.0) I get a message asking me to update my software to 2.6.
When ever I follow the provided link to try to do this I just get an access denied message. I have double checked and my serial number is in my profile as required.
I hope you can tell me what is going wrong as I notice a post from August in FAQ's stating the same issue but it has received no replies.
