The hard disk where your library is located may be full or unavailable or permissions may have changed. To avoid losing your work, quit iMovie.
i have imovie version 10.0.2 for the macbook pro (OS X 10.9.1) i am unable to edit videos because every time i try, this message pops up: "The hard disk where your library is located may be full or unavailable or permissions may have changed. To avoid losing your work, quit iMovie." i have lots of hard drive space left. this is a 2 month old computer. a response would be appreciated.
MacBook Pro, OS X Mavericks (10.9.1)
