Hi Sean,
That sounds a little like a connection problem. How many Jags do you have connected at once? You need to have a termination resistor at BOTH ends of the CAN bus. If you're using the RS232 method, there should be a termination resistor inside the DB9 converter shell between the green and red wires (as in the manual). There should also be a CAN terminator in the "right" port of the last Jag in the bus. Also, TI suggests only connecting at MAX 2 jags at a time during programming.
When everything is connected correctly, should should just be able to click on "connect" from a pull-down menu at the top of the program window. This is all assuming you are using RS232 and the BD-COM program. I would start by loading the new firmware on the black Jag and then connecting a gray Jag and loading the new firmware for it afterwards (it has a different firmware load).
I hope this helps. Good luck.
