Unable to access my VM app on new account number, contract changed by Virgin

Several weeks ago I signed up to Virgin with a broadband and TV package.  I set up the Virgin Media App in eager anticipation of a good install.  However on review I decided to cancel the TV package.  This was done easily by contacting Virgin and they simply set me up with a new account (same number as my original contract just ending in 02 as opposed to 01 on the original account) just with broadband.

My installation took place and everything was set up brilliantly, I now have a great broadband service so happy days.  However I cannot access the VM App using the new account number as my email address has already been linked to the original contract. I have tried setting the app up using a new email address but for some reason this is not being allowed.  Can someone help with this please as I cant manage my broadband service or see any invoice details....frustrating!!
