That other thread listed suggested renaming and that did the trick. My original application was called "BackToTheFuture101 DRM 15.05" (minus the quotes) and after renaming it to "BackToTheFuture101" it worked perfectly (with wifi on and wihtout using the Terminal). If you have any problems, I'd give that a shot.
That's pretty sloppy Telltale. Teach your developers what a relative path is, or atleast check your own support forums. :/
