ProTools11 not recognizing ProFire2626 interfaces..?

I'm running ProTools11 with a MacBook Pro (Retina Display) using M-Audio ProFire2626 Interfaces. Everything was going normal, but earlier today when I opened up a saved session, it said that my I/O's had changed. I opened the session anyway and all of my I/O's, except 1 & 2, were "greyed out" and disabled. I'm a drummer and run 12 mics (kick, snare, toms, cymbals, etc...). When I what I've recorded in the session, the sound doesn't come out of the interfaces...it comes out of my laptop's speakers. My mics are fine...the interfaces' green circles light up when I tap each mic. When I go to PT>Setup>I/O it doesn't recognize the PF2626 interfaces. I'm really not sure what to do, and I would sincerely appreciate some help. I do thank you in advance.
