NI myDaq "drawing too much power."

[squelch]

I broke out my myDaq and myProto today and was going to try testing it alongside my shiny new Virtualbench for EE labs this and next quarter. With nothing at all connected to anything on the breadboard, I tried to run the ELVIS DC Level Output to see if my device was working and to test its reported voltage against the Virtualbench's DMM. I powered it on and, as soon as I flipped the switches on the myProto itself the application warns me: "One or more connections to external power rails are drawing too much power. The operation has been aborted to prevent the device from using too much power." It then cuts off and refuses to power on. 

Nothing at all is connected to the board. Any ideas?

Is your device not turning on anymore?  When you say you flip the switches on the myProto, do you mean when you turn on the power or what switches are you flipping?

I notice this topic is getting a bit of traffic and wanted to update.

I'm not entirely sure what was causing the issue, but it's possible that the absence of a load was freaking the software out somehow. I tested the device with a DMM to ensure that I was seeing expected output voltages, etc, and all was well. The issue went away when I prototyped a circuit for a lab.

Very strange.
