WHERE IS MY PROJECT ?

Hello everyone ! 

I have a disparition problem. In July, I worked on a film project.

It was on the 9-10th of july. I know it because I made an Export.

I know I spent time on it because I had to put a lot of subtitles.

The project was on a Pegasus 32To disc.

But when I openned it again in september, There was not a single trace of the July work,

only a project from june, auto-saves from june. Nothing. Just like I never worked in july. But I know I did...

I searched for .prproj on my computer and on my 2 disks that were connected to my mac in july, but found nothing...

and of course, I wondered if Maybe I could have forgotten to save it, but as I know it took me a long time

to finish it, it seems not probable... And again, where the f... are my auto-saves ????

Well, if you have an idea... Thanks !
