Chart series problem

Hi,
I'm getting error when I try to add series to a chart.
I need to remove old series and add new one each time data is updated.

Here below my code:

ColumnSeries scoreColumnSerie = new ColumnSeries();
scoreColumnSerie.ItemsSource = chartSource;
scoreColumnSerie.XBindingPath = "Date";
scoreColumnSerie.YBindingPath = "Score";
scoreColumnSerie.Color = Color.Gray;
scoreColumnSerie.Spacing = 1;
SplineSeries scoreSplineSerie = new SplineSeries();
scoreSplineSerie.ItemsSource = chartSource;
scoreSplineSerie.XBindingPath = "Date";
scoreSplineSerie.YBindingPath = "Score";
scoreSplineSerie.Color = Color.Red;
foreach (var item in scoreChart.Series)
{
item.IsVisible = false;
}
scoreChart.Series.Add(scoreColumnSerie);
scoreChart.Series.Add(scoreSplineSerie);

I'm getting this exception

Dear Sir,

I'm countinuosly getting this error, it's hard to replicate in your example.
I'm just adding data to a series and then need to remove oldest one and add newest.

Sometimes I'm getting this error stack
