Trying to run Network Threat report, and it times out

When I try to run Network Threat report on SEPM 12, I get the error:

This query could not be processed for one of the following reasons:

 

1. The database query timed out. Try reducing the number of filters, or increasing the SQL Server query timeout value.

2. An unexpected error occurred. Try running the query again by using default filter values.

3. String encoding was possibly not UTF-8, and may result from copying and pasting data instead of typing data. Try typing data in the input fields.

I followed everything in this artical, http://www.symantec.com/docs/TECH101746 , but it doesn't work.
