New Problem with Traktor I've not seen before?

[Karlos Santos]

I never have the crossfader showing on Traktor but could it just be vibration on the vci?

My traktor pitch arrows flash like mad cus of the vibration on the jog wheels.

I'm having this same problem, except I'm already using 320 Mp3s! I've had this same setup (Lenovo G450 laptop/Traktor 2 Audio), for about a year, and it's always worked fine. It first did it to me on stage 2 nights ago (of course), then just did it to me again at home. Hope someone can help, it really sucks to have the music stop right in the middle of a song everyone's getting down to. :/ Thanks in advance to anyone that can help! It will be really appreciated.
