KML styles are not always shown

Very often when loading the below page, my KML styles are not shown:
Page: http://www.digitaltlandkort.dk/
KML: http://digitaltlandkort.dk/kml/municipalities.kmz (http://
digitaltlandkort.dk/kml/municipalities.kml)

My KML XML is valid and I see no JavaScript errors.
Any ideas?
