If you disect the error message it is:
(Text,FontName,ForegroundColor,BackgroundColor,BackgroundStyle,HorizontalAlignment,VerticalAlignment,Bold,Italic,Underlined,AdvancedPlacement)
(Unit,SizeContext,SizeX,SizeY,Rotation,MaintainAspect,InsertionPointX),InsertionPointY
The item's named in the parenthesis must be present at the same time.
Can you try to set the "BackgroundStyle" value? Or Perhaps the
"AdvancedPlacement"?
Also, try to set the InsertionPointX/Y values as well.
Those properties have a InsertionPointXDefined boolean as well, since a
double is/were not nullable in .Net.
If you figure out what is missing, I'll update the MaestroAPI to
automatically insert a default value.
