Since my dissertation I haven't worked with jitter, but it was on Max 6, so I haven't seen any errors about mislabeled files. Try just changing the names?
Maybe do another topic just for that, if someone had the same problem. Sorry I can't be of any help on that.
That is what I meant about the media files, add them after building the application, inside a folder, I probably didn't explain it well!
I usually make my own folders to put any extra files, and construct the path from within the application, just to be sure it uses the right file, but using the resources fold will do just fine!
