Management server showing all clients offline

I am getting this error the week after I migrated my SEP management server from Win 2008 to Win 2012.  It worked fine for the first week but now all my clients are reporting as offline.  I restarted the server and I still get the same problem.

Here is my FUSTRATED part.  I tried to enter a ticket BUT I keep getting rejected because I am entering an invalid version number.  I have tried:

12

12.1

12.1.5

12.1RU5

12.1.5337.5000

I am out of options.  How do I submit a ticket to get this issue looked at....?  I have tried to contact my reps via email and no response from anyone for two weeks.
