iMovie 10.0.1 Share Error -50
I've just completed a movie and have attempted to use the share feature several times without success. I have the options available via the dropdown menu - this is not a mackeeper issue as I've never installed that - but none of them will work. The youtube and email functions never process and the share to theater option gets all the way to the end and then results in a -50 video rendering error. any ideas how to circumvent this issue or another way to share/save out my movie?
FYI - I'm running OS X Mavericks (10.9.1)
