I ordered email defence a day ago but when I try to configure it through my 
123 reg control panel-->modify domain-->manage email defence I just get the
following error:

Sorry, an internal error occurred and we were unable to process your 
request. Please return to the Main page and try again shortly. If this error 
persists, please contact 123-reg helpdesk@123-reg.co.uk.
Is anyone else having the same problem?
