Final Cut Pro X 10.0.6 can't share or duplicate

I have been working on a final cut project, I started it in FCP 10.0.05 and then was informed of the upgrade so the project was finished in 10.0.6. I have tried to duplicate the project to save a back up of the project on my hard drive and the duplicate has error triangles and will not run if I disconnect the external hard drive. I have also tried sharing the project. I have been able to share as a DVD, however, none of the other sharing options work. The project starts transcoding and then it gets hung up, stops making progress. I spent 2 hours at the genius bar in the apple store last night and we were not able to fix the problem. Any thoughts?
