iMovie cannot find vidoes in iPhoto since iOS6 update. It doesn't recognize any videos and all were taken with iPad camera.

I recently updated my iPad to iOS 6. It also updated many of my apps including iMovie. After the update when I opened iMovie, I got an error message saying videos in the project couldn't be located. It then asks if I would like to search for them, which I click yes and then I just get a message that an error occurred. I have even tried to add new videos to this project or a new project and it won't recognize any videos on my iPad, or pictures for that matter. It does find music. All the pictures and videos on my iPad were taken with the iPad camera, no other camera or app.
