Can't get playback on Logic Express 8
I can't for the life of me figure out what is wrong with the playback on my logic express 8. I'm new to Logic, and I have read up and see other people having a similar problem, so i'm guessing this is pretty common? I can't get anything but the click and loops (so i know my headphones are working), i've enabled the device, and gone into my system preferences to make sure nothing is muted (i've also checked the mixer). I can get it to track... but, no sound. Any suggestions?
Thank you,
A
