Hi mhuseby,
Check if the "AT...." boards you are using are supported by DAQ 6.9.X that ships with LV 6.
I believe the last version that supported the "AT..." boards was 6.1.
If this is the case, remove the boards, then DAQ.
Install DAQ 6.1.
Then re-install each of your boards, one at a time, with re-boots in-between.
