Tim,

Thank you for your help thus far. I'm still getting the same error. I tried different combinations of the connection string in app.config with both user name/password and Integrated Security=SSPI. My user has sysadmin rights to this database on the sqlexpress instance.
My ABusinessObject.cs does not really have anything in it - only the constructor where I specify DatabaseKey and DefaultCommnadType.
In my app.config I have key="Whiteboard\DataAccessClass" value="DataAccessSql" and I also put this.DataAccessClass = "DataAccessSql"; in my constructor of ABusinessObject.cs to be sure.

Is there a way to uninstall Business Layer Generator so that I can install it again? I reinstalled MM.NET 3.5 and also VS 2008 but that did not change things much. BTW - a friend of mine working with me on this project does not have this problem so it has to be something on my machine.
