Error when compiling Script

Using the DiagramBuilder example, I open the "Edit Script" form, click compile and get an error:
{"Specified argument was out of the range of valid values.\r\nParameter name: searchString"}
" at Syncfusion.Windows.Forms.Edit.StreamEditControl.FindRange(String searchString, CoordinatePoint startLocation, CoordinatePoint endLocation, Boolean matchWholeWord, Boolean searchHiddenText, Boolean searchUp, Boolean useRegex)"

I made no modifications to the code.

It looks like from the stack trace, the problem is with the ScriptEditForm itself.

Any ideas?
