Using D2SC (PCG) for Exams & Promethean ActivExpressions "no registered devices"

I came across this problem twice this year and was able to work around it:

OK, so I gotta get this blog going. Wednesday I met with my team. Thursday I met virtually with the Texas Instrument people. I'll post the link for the next virtual meeting (Oct. 24th I believe). We talked about using Nspires to quiz. It's pretty neat, you can have Algebra students show their work within the .tns file. As for the meeting with my team, the results were that I have a lot of work to do. As soon as I figure out how to post files on this blog I will start with a scatter-plot template for the Nspire.
