CA-SDK trouble upgrading to Motion Driver 6.1

I'm upgrading my Motion Driver software from 5.1 to 6.1 using the CA-SDK hardware. However when I compile the software using CCS6 and put it on the device through JTAG and turn it on, the Red light on the device stays On constantly. Consequently the cube does not appear when starting the python client script as it did before the upgrade. The Bluetooth does work and pairs up with my PC.

Anyone have a similar problem?

thanks.
