[Untrappable error]

I'm working on a fairly simple chart, but have recently started receiving the following error:

System.DivideByZeroException: Attempted to divide by zero. at SoftwareFX.ChartFX.PaneCollection.PO(IGraphicsEx 2JE, Int32 2JF) at SoftwareFX.ChartFX.1V.PW(IGraphicsEx 2JX, Rectangle& 2JY, Boolean 2JZ) at SoftwareFX.ChartFX.1V.PU(IGraphicsEx 2JS, Boolean 2JT, Rectangle& 2JU, Int32 2JV) at SoftwareFX.ChartFX.0X.OnPaint(PaintEventArgs e) at System.Windows.Forms.Control.PaintWithErrorHandling(PaintEventArgs e, Int16 layer, Boolean disposeEventArgs) at System.Windows.Forms.Control.WmPaint(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

The containing panel for the control starts off as enabled=false. The data is then populated into the chart . Finally a saved chart template is applied and the containing panel is set to enabled=true. My code then exits the sub. A second or two later I trap the above error in my Sub Main(). Any ideas? Could this be a corrupt chart template or something? I've been serializing it to XML for storage in a SQL database. Here's the code I'm using to apply the template:

Private Sub ApplyChartTemplate(ByVal ChartXML As String)

Dim ms As IO.MemoryStream = New IO.MemoryStream((New System.Text.ASCIIEncoding).GetBytes(ChartXML))Me.Chart1.Import(SoftwareFX.ChartFX.FileFormat.XML, ms)

End Sub

And here's the string I'm passing in.
