Win 10, F2012

Hi,

  I followed some old instructions because I keep getting "not responding" messages when loading songs (regular .mus files).

  They said to export as XML, save the XML, close it, then import it and save it as a .mus file.  Didn't work.  Well, it kind of did yesterday, but it keeps ignoring whatever I've exported, and just overwrites the previous piece of music onto whatever I'm working with.  If it's a shorter song, it cuts all the measures.

  It's given me this message:

  Of course, I have to re-load all the instruments individually in the Score Manager ("reassign playback sounds" didn't work).
