Going from FCP 5 to FCP 6 is a PAID upgrade...not something you download. So they either have to try to find it used somewhere, as Apple is now only selling FCP 7, or rely on exporting an XML of your projects or sequences for them to import. XML v3 for FCP 5 to read.
seems to be working. thanks a lot Shane, appreciate the help! I've exported a test to his old FCP right now and it works! hopefully it will continue to works when he exports and tries to come back into my 6.0
