Chris; The FTDI drivers are now maintained by Apple (since Mac OS X 10.9), so there is no need for installing the ones from FTDI. In fact you probably should uninstall them to allow the Apple drivers to do their job.
But this isn’t an I/O issue. This looks like there is a corrupt file the application is trying, but failing to read. There should be a crash dump that was created when the program crashed. Open the Console app (in /Applications/Utilities) and look in the various directories it shows for an appropriately named crash log. That should tell us a lot more. One question - did you try to copy a file from a Windows machine into the Mac for this application? Perhaps David (the app author) might want to jump in here as well. He might have a much better feel for why we are seeing these errors. 73!
