I got a 'Welcome to Free Trial' message from *** Email address is removed for privacy *** that included links to the Windows Azure Management Portal and to a support page at http://www.windowsazure.com/support.  But I cannot use the support link, and I cannot use Azure.  I get an error “We were unable to find any subscriptions associated with your account”.  I can log into the Azure account page https://account.windowsazure.com/Home/Index but when I click ‘Portal’ I get the same error:

Does anyone know how to report this issue appropriately or resolve it?  Also, why isn't Azure listed as a product on this forum?
