Reply to VCI-100 SE + Traktor 3.4 / Pro Crash!

OK, got a very very very annoying problem:

Got the VCI-100 wrapped in the SE Overlay, worked all fine, and got Traktor Pro, also works fine.

Problem is: After a X amount of time Traktor suddenly crashes, gets stuck on one annoying tone and need to turn of my VCI-100 SE to stop the sound. So I guess it's the VCI doing harm.

Can anyone help me out with settings in Pro or maybe something else, so I can go all crazy on my VCI-100 SE again?

My specs:

Dell Lattitude D830 2.4 Ghz dual-core + 2 Gigs Ram
Echo Indigo Dj
Vci-100 SE
