TRAKTOR PRO 3 ERROR

I own a Pioneer DDJT-1, whenever I use traktor for over 5/10 minutes it goes into a slow motion and it ruins the whole track, I pause play, change track but it stays the same, the only way I can fix this slow mo lagging sound is closing the program and opening again, I haven’t found any help online and really need to solve this problem for my gigs. Any help much appreciated
