XamlTune.App crahes..


im trying to convert a (by ms visio11 generated) svg file, but app crashes.   When running it in Debug mode with VS2008 i get the error: XamlParseException: DTD is prohibited in this XML document.   when i remove the DTD in the svg file, i get the error: XamlParseException: Invalid character in the given encoding. Line 2, position 72. => there is a "ü" character: <!-- Generiert durch Microsoft Visio 11.0, SVG Export, v1.0 Hauptübersicht.svg Page-1 -->   when i remove all the "ü" characters and replace them by "ue" (its german), i get the error: XamlParseException: The tag 'svg' does not exist in XML namespace 'http://www.w3.org/2000/svg'. Line '6' Position '2'. => <svg xmlns="http://www.w3.org/2000/svg" xmlns:v="http://schemas.microsoft.com/visio/2003/SVGExtensions/" ..   Q: Whats the problem with that SVG?   Its definitly a working and correct SVG file....
