M-Audio Oxygen 61Logic problem


I'm running 10.4.2 and my controller is an M-Audio Oxygen 61. My A1 key on my controller doesn't work. But, sometimes it works but A2 doesn't work or sometimes A3, or G1 or G2 etc. It happens randomly. I'd rather not get another controller but it gets kind of frustrating. Could it be my Logic preferences? I could do the "reset all preferences except key commands" but I'm concerned with what might happen. I've been using Logic since it was Creator (on an Atari 520) but I really don't know much 'under the hood". Thanks for any help.
