DVS 7 some weird problems

Hi.
I got DVS 7 and from some time i got weird problems with Mixvibes.
I play form vinyls on Technics 1200 & new needles & got Win XP & Msi laptop. I use drivers ESI 1.0.39 for U46 MK2 soundcard.
First thing is that bypass option doesn't work. When i play from time coded vinyls and when i click on bypass symbol i don't hear that special noise from Mixvibes vinyls. I tried to reinstall Mixvibes but bypass option doesn't work.
Second thing.
When i make install wizard and calibrate vinyls i save my settings with mp3 playlist. I read that when i start Mixvibes i can load my settings to Mixvibes and i don't have to make install wizard again. In my MV i have to make new calibrations over & over.
Third thing.
When i got calibrated vinyls on left deck when i play some track everything goes normal. But when i stop vinyl track on MV is going like i was scratching. Track goes backward and forward in couple miliseconds.
But on right deck when i stop playing vinyl track goes backward - with the same tempo like the track is played on vinyl.
It looks like i was playing vinyl backwards. But the track is doing this on it's own.
Fourth thing.
I reinstalled MV and when i play on 5 milisecnods latency tracks are glitching like i had to low latency but i had every program turn off and my Win is reinstalled & fresh.
What can be the cause of my problems ?
Maybe my soundcard is broken (U46 MK2) or my vinyls are to old - i have them from 1 year when i bought MV. Or maybe my laptop is broken or something else.
Please help.
