QAAWS error on Microsoft OLAP Cubes

Hi Experts,

I am on BO 4.0 SP2. I have created a universe on Microsoft SSAS 2008 OLAP Cubes. When I create a report from Rich Client it works all fine. But when I use QAAWS for Xcelsius I get the "getdocumentinformation Exception Database Error WRE 99998

"Error : (CS) Unable to bind to Network Layer Object" IES 10901".

Both server and client tools are on BO 4.0 SP2 level. Universe connection works all fine.

Any idea?

Thanks,

Abby.
