Oh damn ... the next one :-/
Your processor is a Sandy Bridge (
see Wikipedia). For this processor there is a known issue with USB 1.1 audio interfaces, like yours. You can hear the timecode in your mixer, but it is not recognized by the software. We had this issues several times and the only solution is to get a USB 2.0 audio interface as Hercules DJ Trim 4&6 or Native Instruments Audio 4,6,8 or 10.
I am sorry to say so!!!
