I am unable to start the MDS service on the BES due to the following error:

"Could not start the Blackberry Mobile Data Service on Local Computer
error 203: The system could not find the environment option that was entered".

I found a solution in this thread: "blackberryforums.com/blackberry-network/43238-mds-error.html", but it hasn't worked. I changed the registry entry which was incorrect before, and rebooted server, but still can't get the MDS to start.

Is there anything else it could be?

I am running BES 4.0 and latest JavaRE is installed.
