The procedure you sent me did allow me to re boot Roon again and I had a back up - I lost some history but nothing major.
I would like to make a suggestion - my database crashed on July 3rd right before a big holiday weekend when enjoying my music was important as you can imagine - Forth of July. You did not reply until July 7th. I totally respect that the Roon support team has time off especially on holidays. This problem that I encountered and or the solution should be easy found on your support website. The instructions you gave me are easy to do. So my suggestion is to provide recovery procedures easily on your site. Also note that relying too much on forums for support has its downside - you force users to search and read and go through lots of posts etc. and this takes a lot of time for us. It would be great if you can curate this a bit into official support help for common issues that occur. Lastly - i would also suggest you leave at least one person active on support. 7/3 - 7/7 is too long. Thank you for your help.
