Traktor, Crashing and lost Monitor channel after Update

[DjFrag]

After i updated to the latest Traktor 2 version i came into the program and one of the headphone channels was turned off. tried several times to activate them both again, but everytime i get a blue-screen and the computer shuts down. It works fine to switch between one or the other, but not them both at the same time.

I'm running Windows 8 x64, Traktor S4 + F1.

Anyone else having this problem? and/or know a solution to my troubles?

I think there is a fix for this on NI's website
