Let it be known that BES or BPS version 4.1 REQUIRES a certain version of Java. That version is: Java 2, SE v1.5.0_11. You can download it here.
Without this version of Java, you will have many different problems. The problem I was having was with the Blackberry MDS Connection Service not starting. I got the following error: The BlackBerry MDS Connection Service service terminated with the following error:
The system could not find the environment option that was entered.
