NullReferenceException in ChartImpl.cs

Hi, I'm trying to use ComponentPro Word to edit charts embedded in the document. When I call the chart.ChartData.SetChartData() method I get a NullReferenceException in the file ChartImpl.cs. Specifically, this line in the ComponentPro code throws the exception...line 3760 in ChartImpl.cs if (parentChart.Categories.Count > i) { (parentChart.Categories[i] as ChartCategory).CategoryLabelIRange = range2; <===== Exception Thrown here (parentChart.Categories[i] as ChartCategory).ValuesIRange = categoryRange; if ((parentChart.Categories[0].CategoryLabel as ChartDataRange).Range != null) { (parentChart.Categories[i] as ChartCategory).Name = (parentChart.Categories[0].CategoryLabel as ChartDataRange).Range.Cells[i].Text; } } The null reference is being returned by parent.Categories[i]. When looking at the code in ChartCategroyCollection.cs it has the following... public new ChartCategory this[int index] { get { return null; <=== This is why we are getting a null } set { throw new NotSupportedException(); } } I have changed the source code to try and fix this, and it appears to work. public new ChartCategory this[int index] { get { return base[index]; <=== This line is modified } set { throw new NotSupportedException(); } } But I'm not sure if this is the correct way to fix this. I believe I am running the latest version of UltimateStudio-Pro v7.1.233.49, and it includes the source code. Can someone please update your source code and release a new version of the product soon. Thanks
