CRX Viewer error code 0xbe4

[drag0n_45]

Hello.
I'm trying to open a Crystal Report that was originally made in CR5 in a CRX viewer. I plan to port all reports into CRX, so I wanted to use the CRX viewer instead of the CR5 one.

I'm getting this message when I try to open my report:


I'm using the following code to render the report:

Private Sub RenderReport()
'The Crystal Reports "application" to hold the CRReport and control the viewer
Dim vl_CRApp_cra As CRAXDRT.Application
'The Crystal Reports "CRReport" containing the CRReport itself and any changes
Dim vl_CRRep_cra As CRAXDRT.Report
 
 
'Initialize objects
   'On Error GoTo RenderReport_Error
   Stack.Push "RenderReport"
 
Set vl_CRApp_cra = New CRAXDRT.Application
Set vl_CRRep_cra = New CRAXDRT.Report
 
 
'Ensure that parameters are entered and file exists
If (SourceFile <> vbNullString) And (Dir(SourceFile) <> vbNullString) Then
    
    'Open the CRReport
    Set vl_CRRep_cra = vl_CRApp_cra.OpenReport(SourceFile)
    
    vl_CRRep_cra.RecordSelectionFormula = SelectionFormula
    vl_CRRep_cra.DiscardSavedData
    vl_CRRep_cra.Database.SetDataSource DataSource
    
    
    
    'Set the selection formula on the CRReport
    CRReport.ReportSource = vl_CRRep_cra
    
    
    RefreshReport
Else
    MsgBox "Invalid parameters"
End If
 
Set vl_CRApp_cra = Nothing
Set vl_CRRep_cra = Nothing
 
 
CleanUp:
   On Error GoTo 0
   Stack.Pop
   Exit Sub
 
RenderReport_Error:
 
ErrHandler "frmCRX", "Form", "Sub", "RenderReport", Erl
 
End Sub

My thought is that perhaps I'm not setting the report's database location properly. I assume I'm supposed to be using SetDataSource - since it makes sense that the report would want to pull info straight from a recordset.
Is there another property in which I would specify a database file name? I'm a n3wb to the CRX SDK.
