Cross & RANE Sl2

Hello ...
I tried to connect to Cross, the RANE SL2 ..... everything works perfectly!
with windows 7 64 bit, check the CDJ2000 to the beauty of 2ms latency ...
Only problem, I always have to reselect the sound card (Rane SL2) from the control panel, every time I connect to the Cross .... while u46mk2, made the switch alone.
Another problem, if I try to select the SL2 from the panel, if this is not 'connected, Cross is' Crash ..... with "Cross.exe has stopped working"
Help me!
