Crash on MPF startup Cobrapin OPP

[Marty McFly]

Crash log below. I sent it after it happened. Trying to figure out why I cannot start up mpf -b with a basic cobrapin config.

It looks like your machine is looking for an opp: section in your main config file, and can't find it.

[Marty McFly]

You know what. I tried taking some things out of the main cobrapin config file to see if I could narrow it down. If I use the starter config for cobrapin on MPF site, I still get a crash. It appears that it might be an error opening up the USB port?

I just realized when I plug them in I have to define them based on what my computer labels them. So COM3, COM4, and COM5 (for the satellite board)

I will improve the error above as well. It should not crash out hard.
