Why the Crystal Report didn't show up

Why the crystal report didn't show up? I already breakpoint and check line by line and already passed to the CrystalReport1.PrintReport.

What is the possible cause of this? I checked the path it's correct.

If dbcboReport = "Account Balances Summary" Then
        Call Update_Sql
        CrystalReport1.ReportFileName = App.Path & "\..\Rpt\Cs_Bbg_TrxBal_Summary.rpt"
        CrystalReport1.PrintReport
        DoEvents
        cmdOk.Enabled = True
        cmdCancel.Enabled = True
        lblStatus.Caption = ""
        lblStatus.Refresh
        Exit Sub
    End If
