Reply to Problem with PC and Soiks VCI 300 TSI

On my mac the TSI works perfectly but when I import it on a PC and connect the VCI 300 Im only able to choose between 2 channels in the "output router"?? 2 in and 2 out? When I connect my mac I have 4 in and 4 out. Does anybody know how I get to choose between 4 channels so that I can get the output routing correct on the PC? I need 4 in and 4 out!!! This is probably easy to solve but I dont get it!
