PivotCaches.add Error 5 - 2003 to 2010 Macros

I have a 2003 Excel xls file that I am trying to run in Excel 2010. I first saved the file as a xlsm and added the directory as trusted in Trust Center. I am getting an error code in the red. Note: If I change the PivotTableVersion to 12, it still gives me the same error. Code is below. Thank you in advance for your help!

Sub Create_pivot()
    Wbname = ActiveWorkbook.Name
'   Insert columns to make room for pivot table
    Columns("A:I").Select
    Selection.Insert Shift:=xlToRight
    myData = Sheets(ActiveSheet.Name).[J1].CurrentRegion.Address
    mySheet = ActiveSheet.Name & "!"
    tableDest = "[" & Wbname & "]" & mySheet & "R1C1"
    ActiveWorkbook.PivotCaches.Add(SourceType:=xlDatabase, SourceData:= _
        mySheet & myData).CreatePivotTable TableDestination:=tableDest, TableName _
        :="RTP_alerts", DefaultVersion:=xlPivotTableVersion10    
    With ActiveSheet.PivotTables("RTP_alerts").PivotFields("Application")
        .Orientation = xlRowField
        .Position = 1
    End With
    With ActiveSheet.PivotTables("RTP_alerts").PivotFields("Object")
        .Orientation = xlRowField
        .Position = 2
    End With
    ActiveSheet.PivotTables("RTP_alerts").AddDataField ActiveSheet.PivotTables( _
        "RTP_alerts").PivotFields("Alerts"), "Count of Alerts", xlCount
    ActiveWorkbook.ShowPivotTableFieldList = False
    Application.CommandBars("PivotTable").Visible = False
    
    Columns("G:I").Select
    Selection.Delete Shift:=xlToLeft
    Range("D2").Select
    ActiveCell.FormulaR1C1 = "Owner"
    Range("E2").Select
    ActiveCell.FormulaR1C1 = "Problem Ticket"
    Columns("E:E").ColumnWidth = 13
    Range("F2").Select
    ActiveCell.FormulaR1C1 = "Comments"
    Columns("F:F").ColumnWidth = 48
End Sub
