I thought there was a way to see the ticket. But I have been having a dialogue with WiiM (mostly my posts). I've tried everything: Several deleting and re-downloading app, checked for corrupt files on foobar2000, rebuilt library several times (the last after deleting files with .wmdb extensions), malware scan, turning off firewall and virus protection, changing settings in registry editor, then doing a system restore (hoping maybe it would shake things up), checking with a backup USB stick (same thing happens), etc., etc. I've ruled out everything I could think of. I wonder if this has happened to other users of this forum as well.
I guess I should clarify: The external usb drive is connected to my desktop computer, not the WiiM streamer. I use the app on my iPhone and iPad to stream to 4 separate WiiM devices via the media player. All are exhibiting this issue.
