I just got the MobilePre USB from M-Audio and downloaded what I thought was the correct driver from their website. When I installed it, I found that it wis actually the driver for the USB Duo. Now i cannot figure out how to uninstall it from my system preferences. I'm sure that it's creating conflicts, since the dialog box in the Mobile Pre says "unable to connect to M-Audio MobilePre USB. Is it on?" It is definitely on, and I feel that it is installed correctly. Any ideas?
