I have seen this Problem before when, The Particular License for the CAS has not been installed on the CAM.
SEE, There are different licenses for The CAM and CAS but they are generated using the MAC of the CAM's eth0 interface.
So you need a License for the CAM as well as a License for CAS.
If you still find any issues then Do Notify.
See the SnapShot from the Cisco Document.
