iMovie DID NOT save my project. Help!

[whimaway]

So I literally just spent hours putting together a video for school. I exited out of iMovie knowing it was supposed to save the file on its own. I open it back up to check on it and *poof* it's completely gone. I searched my hardrive and the file exists but it will not open with iMovie or Quicktime. Is there any way to recover this video?

Nevermind! iMovie wasn't recognizing the file since I dragged it out of the projects file. hehehe

But does anyone want to tell me how I would go about putting an iMovie project on facebook and then a DVD?
