Audio Interface

Hi y'all,

I have been working with Logic Pro X for a while. Today when I turned on my computer and interface, Logic will recognize the material already recorded. But when trying to record audio or guitar, only the interface (Apollo Twin) will meter the sound. So the sounds are going into my interface but not showing up in Logic channel strips. The audio preferences are synched to the Apollo, and Logic will play back material but not record anything. Anybody have a problem like this.... I was recording the same way yesterday and today its different?
