I need 27 myself now, and upgrades (I have 26) are unavailable.  I would be happy to purchase from you if you won't need it and they allow this.

If you just bought it (within 30 days) you can get a Refund.

NotePerformer can be used in Dorico as well, and I'd probably recommend it because it offers better playback than the stock libraries (even though it may not sound as good in some areas).
