WMP SDK weird message.

[Tyrocx]

Hi, everything works great, but for some reason when the burner starts it says the following:
"There is a problem with a file in your burn list. You can skip the file and burn the other files, or you can cancel burning and try to resolve the problem first by clicking the icon next to the file."

This message only appears if I simply launch the program then try to burn, but if I actually click Play on the windows media player object then click burn, it burns perfectly fine.. so not sure if something is not being initialized.

Below is my code

'********WMP BURNER CODE**********

    Private wmpBurner As IWMPCdromBurn
    Private BurnerStatus As String = ""
    Private StartWMPBurn As Boolean = True
   
    Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        'Create basic playlist
        Dim playlst As IWMPPlaylist = wmpKJB.playlistCollection.newPlaylist("my new playlist")
        Dim track() As String = Directory.GetFiles("C:\Grant")
        For i As Integer = 0 To track.Length - 1
            playlst.appendItem(wmpKJB.newMedia(track(i)))
        Next
        wmpKJB.currentPlaylist = playlst
        wmpBurner.burnFormat = WMPBurnFormat.wmpbfAudioCD
        wmpBurner.burnPlaylist = wmpKJB.currentPlaylist
        wmpBurner.refreshStatus()

        'Validate Disk and Drive
        If wmpBurner.isAvailable("Burn") = False Then
            MsgBox("The drive is NOT a CD Burner")
            StartWMPBurn = False
        End If
        If wmpBurner.isAvailable("Disc") = False Then
            MsgBox("Drive is empty, please insert a blank CD-R.")
            StartWMPBurn = False
        End If
        If wmpBurner.isAvailable("Erase") = True Then
            MsgBox("You are using a CD-RW isntead of a CD-R, do you want to continue?")
            StartWMPBurn = False
        End If
        If wmpBurner.isAvailable("Write") = False Then
            MsgBox("Please insert a blank CD-R.")
            StartWMPBurn = False
        End If
        If StartWMPBurn = False Then
            Exit Sub
        End If

        Try
            'Get Status throughout burn
            Update_Burn_Status(wmpBurner.burnState)
            'progress and status timer
            wmpBurner_PBTimer.Start()
            'Start the burn
            wmpBurner.startBurn()
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
    End Sub

   Private Sub Initialize_wmpBurner()
        'Display Drive Letters in Drive List combobox
        For i As Integer = 0 To wmpKJB.cdromCollection.count - 1
            cboDrives.Items.Add(wmpKJB.cdromCollection.Item(i).driveSpecifier.ToString)
        Next
        If cboDrives.Items.Count <> 0 Then
            cboDrives.SelectedIndex = 0
            wmpBurner = CType(wmpKJB.cdromCollection.Item(cboDrives.SelectedIndex), IWMPCdromBurn)
        End If
    End Sub

I didn't include the instance declarations and other functions since they are irrelevant. I traced the error which is a windows media player prompt that is occuring in wmpBurner.startBurn() I am using 12 mp3 files as test music and none of the files are corrupt. Please help

Thanks!
