So at work I was given a half built quad that someone who no longer works here started. Problem is I've only built/flown fixed wing aircraft. I need to get some help to make this things work. I've found very little help on the internet so far and I'm hoping someone here can assist. Thank you

Equipment: (as far as I can tll, all but the TX/RX and battery came in a kit)
Bumblebee-C
Bumbleebee 930KV motors
Flight controller
E-Flite 3s 11.1v 3200mAh battery
Futaba 6Ex 2.4GHz Tx with RX

I've followed the instructions, which are not user friendly, as best I can. The quad is assembled and my main problem is getting the motors to start. I followed the CSC start instructions and it doesn't work. I've installed the software that came with the quad and i can see on the computer that the tx/rx are working properly because i can calibrate the stick throws and it sees me moving them. I am getting a PMU-ERR error, I've checked the battery connection, but what is a PMU? If i can get the engines started I think I can figure the rest out.

Thanks for your help.
