Upgrade CUE on UC500

Alright, so they finally made CUE v3 available for the UC500 and I want to play with the new features. I also grabbed the CCA 1.6 and wanted to test out the upgrade option in the CCA. So I downloaded the UC500 files and let the magic of the CCA upgrade my UC. Enter problem.

My CUE module won't come up now. It failed the upgrade so I power cycled the UC500 and when I look at the status of the service module it's stuck in "Service Module is waiting for the registration message" and it will eventually tell me that it is in a failed state. I tried reloading it. I tried reset it and I've rolled back the IOS upgrade.

Anyone have any links or ideas on troubleshooting this?
