Chandra,
Thank you for posting! Looking at your two error reports, they seem to be two very different issues.
For the first one, I'd address to see if you have the correct firmware (based on your screenshots it seems like you do but just to be on the safe side). The below link has more information.

In terms of the second issue, there might be a misconfiguration of the Trigger functionality. I've included more information below including sample problems to get started testing.
