Oh yeah, we already did this for 7.0.6. 
Same error in 7.5 with this file.
But- I’m not sure Cubase’s import function is necessarily to blame here.
Cubase for some reason garbles the first measure. In fact, neither staff imports correctly, as I said previously.
I then imported other files downloaded from MusicXML Sites: A List of Sites with Sheet Music in MusicXML Format and the import worked well. ( http://downloads2.makemusic.com/musicxml/ActorPreludeSample.xml and the file attached to this post)
Cubase is on a lower version of MusicXML than Finale (whose manufacturer maintains/owns MusicXML) incidentally. I wonder if this has something to do with it.
