Crystal Reports Invalid Report File Path

Message

Using VS 2008Trying to create report with ASP.Net for website.

Code:
Dim taPetClient As New DataSet1TableAdapters.PetInfoTableAdapter

Dim ds As New DataSet1
Dim PetitionReport As New CrystalDecisions.CrystalReports.Engine.ReportDocument
Me.taPetClient.Fill(ds.PetInfo)
Me.PetitionReport.SetDataSource(ds)

        CrystalReportViewer1.ReportSource = Me.PetitionReport
I am getting the "INvalid Report File Path" error message on  the line Me.PetitionReport.SetDataSource(ds).

The Fill statement above the line that is crashing seems to be working since when I break the program at that point the table has the data in it.  

Any suggestions would be helpful
