I would look at the following:
the CCM client setup logs in C:\Windows\ccmsetup\logs
clientlocation.log and locationservices.log in the C:\Windows\CCM\Logs folder
did the MP role installation complete successfully? - check the MP status in the console and the MP logs on the MP server in SMS\Logs
is the client assigned to the site?
Attach the logs mentioned above if you are still having issues.
