SEP 12.1.2015.2015 & LiveUpdate Administrator

Hello:

Since upgrading to 12.1.2015.2015 in my test environment, test clients have not received updates from our LiveUpdate Server.  In the LiveUpdate Administrator, I currently have Symantec Endpoint Protection v12.1 selected in My Symanted Products.  Does 12.1.2015.2015 require another product selection such as v12.1 RU2 or v12.1 (Beta)?

If this is the case, can I remove Symantec Endpoint Protection v12.1 from My Symantec Products?

Thank you,
Anthony
