[ddots-l] big problem

I'm working on a project. I Don't know what happened, but it seems like the 
whole thing vanished. When I go in to the event view, all the data is there. 
When I go in to the track manager, all the check boxes are checked like there 
suppose to be. When I hit play it doesn't seem to move pass 1.1. So I tried to 
unfreeze the tracks but when I go to the track properties dialog and I arrow 
down to the unfreeze track, jaws says unfreeze unavailable. I'm out of options 
so I need help.
