VS2010, against SQL 2K8 R2 - login failure when adding subreport.

Question

I have tried a number of ways to get this to work.  Is there a set of instructions that can be followed to render a CR with a subreport?
I can create CR reports that run.  Can create subreports that run, but a CR containing a subreport will not run on the server.  Fails with a variety of errors, depending on whether I am using XSDs, OLE-DB or DSN connection.  I give up trying different methods and looking all over the internet for fixes.
What is the preferred method of connection?   I am using stored procedures, and typically have no prblem with RC, but I have to adwit - this- is the first time that I have tried a subreport.
I just cannot beleive how difficult this is to push into a non-dev environment.  Maybe I am missing something simple . . .
Dev: VS2010 on Vista.  CR SP1.  Server: Win 2K8 R2 Ent, SQL 2K8 R2
Thanks!

        'Set the connection information on each table
        For Each table As CrystalDecisions.CrystalReports.Engine.Table In report.Database.Tables
            Dim tinfo As TableLogOnInfo = TryCast(table.LogOnInfo.Clone(), TableLogOnInfo)
            tinfo.ConnectionInfo.ServerName = serverName
            tinfo.ConnectionInfo.DatabaseName = databaseName
            tinfo.ConnectionInfo.UserID = userId
            tinfo.ConnectionInfo.Password = password
            table.ApplyLogOnInfo(tinfo)
            If table.Location.IndexOf("."c) > 0 Then
                table.Location = databaseName & table.Location.Substring(table.Location.IndexOf("."c))
            Else
                table.Location = table.Location
            End If
        Next
    End Sub
Found the ApplyLogOnInfo on the internet, but it doesn't help.  the error I am getting is this:

I am going to give the above a try as well.  Hopefully you see something obvious wrong here . . .  Thanks again!
