Adminstudio 7.0 Conflict Solver

Hi All,
I am using Adminstudio 7 professional Editon. Now i have to use the Conflict Solver in this.I am having SQL Server 2005 for my database.Can any one guide me on how to connect a new application Catalog (SQL Database)to the conflict solver.

I have tried so many times in different ways. Each time i get any of these errors or warning.
1. “Can not open database “DB name” requested by login. The login failed.”
2. If a choose an already existing Catalog, it says “This is not a valid workflow/Conflict solver Database”

Kindly help me to work with Conflict Solver and SQL Server 2005.

Thanks in Advance,
Janarthanan.G
