License Error: mocha AE CC when opening quicktime mpg4 movie created by keynote

UPDATE - discovered answer myself. I set "Open with" and then chose Quicktime. It's not a keynote issue but how my mac is configured. For some reason it had defaulted to using Mocha AE as the application to play MPG4 files, and changing this has fixed the issue for now.

ORIGINAL NOTE:

I exported a keynote presentation as quicktime. Then when I try to run it I get a "License Error: mocha AE CC must only be launched from After Effects " warning. I have Adobe CC installed, but this only really concerns Keynote and Quicktime. Any ideas?
