SONAR X3 and the SI Expression 3

I recently purchased the multi digital expansion card for the Soundcraft SI Expression three. It delivers 32 mono channels of recording to my Sonar X3. However, my Sonar recognizes it only as a 16 in, 16 out device and shows left, right, and stereo inputs for only the ODD numbered channels (1,3,5,7,etc.) Anyone know how I can get Sonar to recognize the 32 mono channels? I've got a live recording coming up in ten days and really need to find a solution......thanks
