Mixvibes 7 acting strange on 1 channel

Hi!
I've been using Mixvibes 7 with pleasure for a couple of years, but lately 1 channel is acting strange.
I am using Mixvibes with 2 Technics SL1200, timecoded vinyls and my Reloop mixer and the U46MK2 soundcard.
Now whats the problem:
Sometimes 1 channel is having trouble with reading the vinyl, he can't always read the begin point of the record and when he can find it, the sound suddenly randomly starts to reform / corrupt.
It is also visible on the BPM counter in the software.
Does anyone know this problem? and more important: what can be the sollution?
I added an configreport.
Thanks!
