Playlist files not pointing correctly

[Demonkunga]

So after installing version 3.1.6336, my playlist files are damaged and no longer point to my music. But as far as I can tell, they haven't changed since 3.0.6335. I'm not sure why this is happening. All I can say for sure is the issue is in the MusicBee.exe

I don't see how an upgrade to 3.1 can damage your playlist files.
Anyway if you want to revert to an older version to see if that makes any differences:

the library database: musicbeelibrary.mbl is copied to musicbeelibrary.preupgrade in case you need to undo the upgrade and revert to an older MB version

Have you tried using Remap Music Folders to relink the files?  Even if they haven't moved, it might help MB find them.

I did a bunch of testing last night. Wasn't sure how to fix the issue, so started from scratch with MusicBee, then after setting everything up, I took a backup and used the patcher for the new version. It made my playlists not point correctly. So I started swapping out changed files from my backup, and MusicBee exe made the difference. With the new one, they're broken, with the old one, they work.

so your library files are ok, just not in the playlists?
I find this all very surprising as I cant recall anything around playlist read/write that has changed between v3.0 and v3.1 and a lot of people have already updated without issue.
Could you send me a zip of the following files:
- MusicBee3Settings.ini (help/support/view settings)
- MusicBeeLibrarySettings.ini (in the root music\musicbee folder)
- MusicBeeLibrary.mbl
- one of the playlists (.mbp)

and the file paths for the following:
- the full path of MusicBee.exe
- the full path of MusicBeeLibrary.mbl
- the full path of the playlist
- the full path of one of the files referenced by the playlist

[Demonkunga]

Sure, will do as soon as I'm home in a few hours.

Yup, library plays fine, just the playlists aren't pointing. I included a picture of the "error" when trying to play a file from a playlist.
Also MusicBee_Setup_3_1_6336 is the correct file isn't it? I don't need to run the one before it in that thread, do I?

D:\Dropbox\Apps\MusicBee\MusicBee.exe
D:\Dropbox\Apps\MusicBee\Library\MusicBeeLibrary.mbl
D:\Dropbox\Apps\MusicBee\Library\Playlists\Bad Seed Rising.m3u
..\Music\Bad Seed Rising\606 - Ep\1-01 Eat Your Heart Out.m4a

Also, I use .m3u playlists instead of .mbp and I'm using portable MusicBee if that makes a difference.
My music is organized by MusicBee at D:\Dropbox\Apps\MusicBee\Library\Music
Relative paths for playlists isn't checked in the settings.

thanks for providing all those files and info.
There is an introduced bug in v3.1 for when library playlists are saved as .m3u files
This should fix the issue:

unzip and replace the existing musicbee application files

Thanks so much Steven!
