No Sound Coming Out of my MPC Live At All

I just spent an hour or so making some music with my MPC Live and everything was going well and then all of a sudden I got no sound at all. I could see on my Audio Interface that there was no sound being sent out of the Left and Right outputs, so I switched to headphones, and again, no sound.

I turned it off for five minutes and loaded a default project and still I'm getting no sound.

I can see on the TUI that the sound are triggering but for some reason, no sound comes out at all.

I am running the latest firmware (updated yesterday).

I have also checked all my cables and the master volume, all appears to be correct.

Is this a known issue? Can anyone help me out at all?

Update: I left the unit for 10 minutes or so and booted it again. When I started it this time i got a message I had never seen before on the TUI which read something like "Updating Please Wait". At the time only the power cable was plugged in and there was no computer connection. After about 15 seconds the message disappeared and I was able to load and here demo projects without any issues. Has anyone else experienced this issue?
