License error

[mugpar]

When i login to plesk it tells me, You are currently operating with a limited product license that requires registration prior to activating the full feature set. To update your product license select the Retrieve Keys option from within License Manager.
So then i go to retrieve key, and it says, Licensing Server Unreachable: Unable to connect with licensing server.
Please make sure that your network allows communication to ka.sw-soft.com:5224.
For more details check system help pages.
This is on 1and1.
Any ideas?

If you have a firewall, be sure to have port 5224 open. That's the port used by Plesk to "phone home."
