Reply to Traktor Rollback Problem( Deleted my track collections Plz Help!)

I've tried searching for, for the answer on this on NI community s can't seem to figure it...Apologies in Advance if it's been covered

Anyhoo I believe it decided to upgrade on it's own when I reopened it (although not to 2.5 ,2.1 something and I lost all my track collection like my 500 favorite tunes that I play on the reg, now it just has some prestock one shots.. when I did load some of my favorite track back in the saved cue points are there but I want to go back to the old software and old archived collection! Are there any reversion methods?

I'm trying to do this ASAP as I'm about to play an audition set for a club later to day. Murphys Law in effect of course.

Please and thank you.

Long time reader of the site and community s and you guys have helped me immensely with the articles, questions and answers!

OK!!!!!!!!! Update!!!!!!!!!!
I got the right software back but my track collection is still blank, also my effect layout is a bit different looking. I'm also using the Most popular S4 User Mapping Thanks!
