Editing Issues: Update 1

This morning when I first came into class and logged onto my groups Mac and opened iMovie the screen was still the same as we left it, I tried force closing it and when I reopened it the same message appeared. So I enlisted the help of one of my Media teachers (Ms Foster) she also tried force closing it and suggested restart the computer. I tried this a few times but nothing seemed to work, however, I've run out of time as I've got to walk over to Grammar to film some more scenes; so one hopes by next Wednesday it might of had enough time to work itself out.
