activation key error-"The underlying connection was closed: An unexpected error occurred on a send."

activation key not working- “a problem has occurred when contacting the licensing server: The underlying connection was closed: An unexpected error occurred on a send.”

Me too, Windows server 2003 32 bit. eM Client runs fine in server 2003 but the license will not activate. HELP !! The error is :

A problem has occurred when contacting the licensing server. The underlying connection was closed. How to we apply the license ?

I know that eM Client no longer supports XP as that OS cannot connect to the license server.  Server 2003 is essentially XP for the server, so my guess is that it too will not connect.
