I normally have it on \Music since that didn't work i tried \Documents and it was the same thing, i may try just leaving it on c:
Right now i'm using the old library, from my old install in \Music, i didn't delete it just in case and that allows MusicBee to start normally, i can play music, change the layout, etc. except i can't make changes, like rating a song, it tells me "access to the path is denied" and so i can't rate it, after trying to change anything of the files and closing MusicBee i get:
Error
Unable to save the library database:
Access is denied.
[C:\Users\"user"\Music\MusicBee\MusicBeeLibrary.mbl]
OK
So basically, something is keeping MusicBee from changing anything.
I'll create a new library in C: and see how it goes.
