Redirecting endpoints to new Enterprise Console

Hi

I'm trying to run the script from http://www.sophos.com/en-us/support/knowledgebase/116737.aspx. to redirect our endpoints from one Enterprise Console to a new Console.  I've entered the relevant config but each time I run the script I get an error "Router is a server router, will exit"

Full log:

I've had a look through other threads and they suggest either the script isn't run as Admin (this is) or there is an issue in the registry (taken from another thread): 

"The script checks the registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\[Wow6432Node]\Sophos\Messaging System\Router\connectioncache.

On a client this is 10.  

On one of the above it is 20512.  As it is typically unwanted to redirect a management server or relay, the script exists if the value is not 10."

This key doesn't exist in the registry.

Can anyone give me any advice please?  Thank you :-)
