Reply to Traktor 2.6.1 not opening on mac and have a gig tonight

I have been working on some playlists over the last couple of days and last evening went to open Traktor and it came up with a error page and on my mac . I clicked to reopen and the same thing happens over again and again , I tried using time machine to reinstall but it doesn't work either . I have managed to get 2.6.0 working but I have lost all my playlist from my track collection . I tried installing the 2.6.3 update but that hasn't helped either.
