imovie problem

Im trying to upload videos from iphoto into my imovie. When i open imovie, it asks, like it should, "do i want to import iphoto video files into imovie?"

Of course i do, i click Now.

then it imports. then this thing pops up saying that it "cant find a certain file" and the videos wont be in my Imovie. i dunno what to do. does anyone know??


i screenshotted what its saying.

Drag the File from iPhoto to the desktop,
delete the file,
empty iPhoto Trash,
drag the file back into iPhoto,

try again.
