Can't share in iMovie 10.1.2 using El Capitan - HELP!

Ok so I have edited together a piece which is around 5 minutes long and go to share and nothing is in the options available - just all grey. I have tried sending it to FCPX but it throws up a missing file error.

I really need to export these videos to files for a project I'm working on. Anyone have any easy fixes?

Thanks

Adam
