playlist folder disapperead and music bee System.IO.EndOfStreamException:

[Fabio]

hello, yesterday suddenly i open the portable version of MusicBee and i received this error message
music bee System.IO.EndOfStreamException: Unable to read beyond the end of the stream.

i then open the portable version on a different PC and it started working but an entire folder containing 7-6 playlists has disappeared. all other playlists are still there.

any idea what may have happened? any help?

the description you give and error message is too vague. MB wouldnt delete the playlist folder unless you deleted it from the left navigator and event then the folder needs to have no playlists.
You might check the recycle bin
