Importing Scenes... I must be missing something

Hi Nic and community. A friend of mine just got MidiFire and wanted me to share some scenes with him to help him ramp up. I had no problem sharing/exporting/etc., but neither of us have been able to figure out how to get his copy to find the .mfr files. We've got them in both iCloud and DropBox. He's an Apple app developer himself, so he should be better at this than I am, but we've decided we're going to give up and ask you. Any pointers beyond the "usual" method mentioned in the Help manual? Also, do we have to be running the same versions? I'm on a Beta release, but since the file extension is the same I didn't think that would have much effect.
Thanks
Tom
