Upgraded osx Mavericks, have LE 9.18, having problems getting signal w/ Profire 610

Everything looks normal. Profire shows signal recognition. Profire mixer window shows signal. Logic Express shows Profire 610 as an option for audio input and output (which I have selected). But when it comes to actually getting signal into Logic there is nothing. (Yes, Input select and Record Enable are chosen). Everything is how I've had it in the past, but the only difference is I upgraded to OSX 10.9. Today is the first time I've tried recording since upgrading the OS. Yeah, I know I'm late to the party. I've seen lots of people are having similar issues. Is it LE9? The M-Audio Profire 610? Mavericks?
