Thank you for sending your database over, I have forwarded it to the QA team for closer inspection. Please leave this database uploaded to your link until QA has had a chance to review.
It may take a bit of time for this to reach their queue but as soon as I have any new information to share I will be sure to let you know, in the meantime you may want to use a fresh database on your QNAP.
How has this part of testing gone? Are you able to successfully use the existing database on your Windows Core as expected?
