Final update. The buyer was given 12 original sequences from my 2008 show which better matches a smaller show setup. I explained how the music needed to be purchased and this was just the rights to adapt these sequences and no support or guarantees whatsoever were included. I provided a private Dropbox link to a zip file. Buyer agreed to drop the case after the download was completed and did so. All is well, but I did learn a lot in the process.
