DB objects' schema change

Hi,

I'v installed nopCommerce, and I should change DB objects' schema from dbo to another dbuser. I change schema in SQL Server 2005, but the application stops with "stored procedure not found" error. I don't know what I should do in web application to work properly!
anyone know?!

Thanks for your help!

Schema of all database tables should be dbo.

I want to modify stored procedures' schema.
What is the solution of this situation?
