Whoa... So my QU24 has lost it's mind (HELP)

My Qu24 has been a workhorse for live and studio since it was released.
I updated my oS to Yosemite about a week ago and was running full speed with
everything working. Today I rebooted my machine, and the QU24 took a huge dump
on all of my audio from the laptop. The drivers, firmware, are up-to-date.

I’ve changed USB cables, directly connected it to the machine, rebooted several times and
the driver from the QU24 send a sample rate of 0 to all the DAW’s and programs using the core audio.

I’m gonna attach a screen shot I captured from Live 9.1.7 that shows the error.

Please help, i’m on a deadline and this isn’t making the process any faster.

Have you tried a hard reset of the QU? You haven’t mentioned firmware or a firmware upgrade, but 1.71 is worth a try…
