Hello Kat,

After I installed GPO, Notation Composer will no longer open. When I open up GPO Studio, it explains that it could not find any Garritan libraries, and to please reinstal GPO. I did this, and nothing changed.<!-/quote-!><hr size=0></blockquote>My understanding here is that the basic problem with Notation Composer now is that it will not start.

The first thing to try is restarting Windows, which is a cure for so many installation problems, such as might have been caused by the GPO or Kontakt Player installers.

If restarting Windows doesn't help, then I suspect that Notation Composer is severely confused about the GPO MIDI devices (Garritan Studio 1, Studio 2, etc.). If that is the case, then Notation Composer is at blame. You can probably work around this problem by deleting the file named mididev.cfg in \Program Files\Notation\Composer. Also, if you find a same-named file mididev.cfg in the parent directly \Program Files\Notation, then delete it also.

Please let us know which of the above cures the problem for you, or not.

Cheers
