Issue loading database on mac mini

Can’t use Roon because “there is an issue loading your database.” Please let me know what specifically to do. I have a Mac Mini running 10.11.4 with 16gb of RAM. Have not had any issue till now. Re-installing doesn’t help. I have no problem starting over. Just tell me what to do.

This message indicates that your DB is corrupted. Usually reasons of such issues are problems with the hard drive or other hardware. I’d like to check you logs to verify the issue. I’ll contact you over PM shortly.

The workaround here is to start from scratch or restore your DB from the backup.

i have the same problem today, I use Macpro.
Could anyone give the solution, even reinstall Roon
