Error when trying to play/open a specific playlist (.mpb)

[Nubblez]

Heya

I recently ran into an issue where MusicBee refuses to open a specific playlist (all the other ones work fine).  I'm not sure if this could be related to one of the more recent builds, or if something is wrong with the playlist file itself.  Even if I go back to an older build, that playlist still won't open.

Could it be related to the length of the playlist?  It had a much higher track count than the others.

This is the error that pops up:

MusicBee v2.5.5457.37571 (Win6.2), 11 Dec 2014 20:50:

i would say the playlist file is somehow corrupted. There was one bug where certain .m3u files were not converted to .mbp formated playlists, so it might be worth opening the file in a text editor. If its readable then its a .m3u file and if you open the file with another player you can copy/paste the links into MB.
Otherwise the file will be corrupt

Thanks for the advice!  Looking at it with a text editor, it looks like it's completely corrupted. Ah well, it's not really that big a loss. From now on, I'll just remember to make a backup every now and then.
