Hi @Larry,
Thanks for taking the time to write in. Unfortunately, there appears to be database corruption within your current Roon database.
To put it simply, database corruption means that the records Roon is reading from your database are different from what was originally written.
This isn’t common and can happen for a number of reasons, like failing harddrives or an unstable power source (frequent outages, hard power cuts, etc).
If you restore from a backup and still see “There was an issue loading your database”, try restoring from your oldest backup.
If you’re not having any luck with your oldest backup, then the only alternative is to start with a fresh database.
If you can, take note of when you noticed this issue starting, and reload from a saved backup prior to that date.
