Thanks All,

I had also found that BIAB didn't have a problem with the MIDI files in question, but had forgotten to mention it.

It does not appear to be any kind of a permissions issue. It is something in the first track that RB 2016 is choking on. When I get a chance I'll try to look at the track content in another MIDI DAW, but I've also ping'd pgmusic again letting them know that deleting the first track from the MIDI resolves the issue and that they may want to look at the content of the first track and see why RB 2016 is choking on it.
