Software worked last week but now it crashes every time remote camera is connected

Please help. My 4th grade students are using this software to make a movie.

I had to revert to the 3.6 to get them to connect the first time but now nothing works.
I applied for the beta testing but no one has responded.

Please help me get this working. I have five 4th grade classes depending on this!

Is no one looking at this? Come on, I need some help.
