RDS Licensing - 'error code 800' error

I am trying to generate a CAL pack ID at <a href="https://activate.microsoft.com/">https://activate.microsoft.com/</a> but keep getting a 'error code 800' error. The product ID of the Windows Server 2012 server RDS license server is 00184-90000-00001-AT620. I called up the Microsoft Clearinghouse number and I was advised that they are getting the same error and that I should call up Microsoft Support. Any ideas about this error and a possible solution? (The Microsoft Support number of 13 20 58 in Australia is clogged and they are not taking any calls).
