HAT issue after SP2   

After installing BziTalk-2004 SP2, When I try to run any of the query from 
HAT. I am getting the following errors.

“The Tracking database on SQL Server <<ManagementServer name>> / database 
"BizTalkDTADb" is incompatible with the expected schema version of this 
BizTalk installation. Because of this some of the reporting view 
functionalities may not perform correctly.”


And 

“Health and Activity Tracking is about to load a saved query containing an 
SQL statement. It is not safe to run queries from untrusted sources. 
     Click Yes to load and run the query, click No to load without running 
the query, or click Cancel to do nothing.”

Can anyone help us in knowing what could have caused this errors?
