Kodi 17 “Database migration in progress” for hours

Hello,

I just upgraded on Windows 10 using the new Windows Store method, but I didn’t get past the initial “Database migration in progress – please wait…” screen. I eventually gave up and uninstalled Kodi 17 and then reinstalled it using the installer. I get the same problem – it’s been on this screen for 18 hours. I previously tried killing the app and restarting it but it made no difference.

Help!

Thanks,
Ed
