The Track is not record enabled!!

[regman39]

Hey guys, I'm having MAJOR PROBLEMS with PT 10! I have a Mac laptop with OS 10.7.2 and an interface Mbox mini 3rd Gen. and of course, Pro Tools 10.0.0. I have headphones hooked up to my laptop when I'm working with my software and it worked fine...ONE TIME! Then after I recorded two tracks I started having problems getting an error message after I added more tracks. Even after I tried creating 8 DIFFERENT SESSIONS I get the same thing! Another thing, when I connect the inputs from the interface to PT, it doesn't have inputs 1 or 2...just 3 and 4...what gives with that?? Anyways, after I connect those inputs, then click on the record buttons I get the error message: The track is not record enabled because it doesn't have both the input or output connections assigned. I've checked EVERYTHING in the outputs of my system preferences and even reinstalled the driver for my interface and NOTHING CHANGES!! The audio works for everything else on the computer, but not for PT 10. I can't even get the CLICK TRACK to work and it also worked ONE TIME! I want to record from pro tools, but it won't let me do anything at all now!! I NEED HELP PLEASE!!!...any suggestions???
