Reply to TSP 2.5.1 unable to save track collection or playlists, 2.5.0 works fine

Quick question...

I've had to revert back to 2.5.0 because 2.5.1 refuses to save the track collections or playlists.

Traktor is giving me an error about not being able to write to the disk...


I first noticed it when a few of my playlists were red... thought nothing of it, imported some new tracks, made some playlists. Quit 2.5.1, relaunched it later in the day and playlists were gone...

trying reinstalling 2.5.1 , and had the same issue.

any one else running into this?

currently running a 2008 macbook on Lion 10.7.4.
