mydaq digital write

[WyoEng]

I'm trying to use a myDAQ to send digital outputs to three heater controls, to turn the heaters on an off with the digital signals.  After trying to use the regular DAQmx express vi and not having any luck, I read about the NI Elvismx express vis in the myDAQ user manual.  Yet still we can't get the vi to work in our program to communicate with the myDAQ device and send out the necessary signals.  We're trying to use the Elvismx Digital Writer.  Attached are the two error messages we've gotten.  If anyone can tell me what we're doing wrong and/or offer any advice/suggestions to fix the problem, I'd greatly appreciate it.

Thanks!

I can't read the second error message, but the first one appears to be a USB connection issue.

Have you followed the instructions on the myDAQ Setup and Support page ?

This will tell you if the connection is working.
