Traktor keep forgetting Collection

Every so often, Traktor forget my collection, and is an absolute pain to reconfigure. To either manually put my entire library back, or reload an backup collection takes WAY TOO LONG. Itunes sync has to be done with only so much songs at the same time because the program becomes unresponsive and has the spinning waiting wheel going on. And if I reload an old collection it will be writing tag forever! And it slows down the entire program. It manages to play the music, but the entire program becomes terribly slow.

If it happens before a show, I cannot redo it in time.

I would like to know what could be causing this? Because most of the time it is allright, and it load my collection properly, but sometimes everything is at (0). And I would like to know why this could be happening.


I run a macbook pro retina 2014, 13', on macOS 10.13.2, and Traktor 10.11.2

 

I get the same thing.

If you right click on Track Collection, then select Save Collection, that might help. Although best to do it and leave your computer running overnight to save the entire collection...

C'mon NI help us out!
