Receiving 'NoneType' object has no attribute 'close' error on startup

Hi,

Super excited to see what you have built. I'm trying to run masseffect2 in a virtual machine. Does it require to be connected to an actual pinball machine for the code to work?

Here's the output from running it:

I get this error when I run the following:
mpf game -t -X

Ok, I figured this out by changing the machine types and other settings in the config file.
