Kodi not scanning library – Settings not stored

Hi guys,

I had to factory reset and reconfigure my NAS because of some file-corruption. I reinstalled and reconfigured MySQL as well. I checked the advancedsettings.xml and sources.xml and they seem to be ok.
When I open Kodi, the library is empty. When I add a new source, I can connect to my shares on my NAS (nfs://192.168.1.13/DATA/Video/Movies) but when I finish the settings for content and scraper, nothing happens. Kodi asks to rescan the library, but it doesn’t do anything and the content and scraper settings are not saved either.
I’m using the Windows Store version which was running fine before I did the factory reset of my NAS.
Any idea’s? Huh
