Issue with MWS

Hi,

I am facing an issue in MWS.
When i try to check Business overview in Administration tab it works fine.

But when i am trying check Business Overview from Monitoring tab i get the below error.
Error executing search. Have a System Administrator verify the Analytic Engine settings at Administration -> My webMethods -> System Settings.

Analytic engine is in running state.Earlier it was working fine.

Thanks in advance.
