I get this, too

I am using 6.5.4. I see the album in the freedb results, but clicking Preview and Add results in the error message and this session log

I would like to change from freedb.mygenres.com to freedb.freedb.com but when I do this in Preferences the change is saved but this session log suggests it did not take effect. I wonder if that is the issue.
