Calibrating issue (Quality 0%)

Hi, I'm a new customer of mixvibes.
I'm using 2 classic turntable and windows 7 x64bits and I've got a problem with calibrating.
I checked hundred times all the connections I tried to switch them I tried the new driver for my U46MK2, I also tried uninstalling and instaling mixvibes again... Nothing... Quality is still on 0% on both decks and it keeps asking me to set the pitch to 0 even if it's allready done... And there is another problem since I installed the new driver, I can't change the buffer size
Please help me
