Ted,
Hopefully you found a solution already, but in case anyone else finds this post I wanted to mention some testing steps that anyone running their own BigBlueButton server should try first. I recommend installing the BigBlueButton API demos on the server and testing BigBlueButton using the demos.
If you run into problems using the demos it's probably your BigBlueButton setup at fault. Then you should head over to the BigBlueButton discussion groups for help.
