It kind of sounds like the service that is installed when you setup RWA is not running.
Are you using your own domain name or the generic Microsft-supplied .remotewebaccess.com?
If you are using the Microsoft-supplied scheme, you are on a dynamic Internet address, and the ‘Windows Server Remote Web Access Administration Provider’ service is not running, your system won’t be able to update the RemoteWebAccess servers with your IP address.
Also, if you are running any kind of AntiVirus solution that also manages your firewall, it may be blocking activity and may require a fixed rule be implemented.
