You can also set the interface in the application by going to the Network menu and selecting Set Device (though I don't think SEQ will start with an invalid interface in order to get to that point - so maybe that should be considered a bug). And it *should* save as part of the preferences so you don't have to keep specifying it, but I'm not 100% sure that works like that, either. It's something I've been meaning to investigate but I haven't gotten around to it.
I can confirm SEQ will not start with an invalid interface. The workaround was to edit the showeq.xml file in .showeq folder with the proper interface. Once that was done, ShowEQ would load and you can manage the interface name from the Network menu option as cn187 theorizes.
