Crystal Reports and VB .NET

I am trying to create a Crystal Report in VB .Net, but keep getting the Database Login Screen. Even after entering data in the fields on that screen for the server, database, userid, and password, I get "Logon Failed".

But, if I design the exact same report using Crystal 8.5 and then set the reportsource of the viewer to that report, it runs fine.

I am reading just 1 table from a SQL database. I am also the owner of the table in SQL, so there should be rights issues.

Any ideas would be appreciated.:)
