Flash problems

1

I don’t know what’s wrong or if I can redeem this, but if anybody has any suggestions please let me know. I working in Flash for a good two hours, I was saveing about every 20 to 30 mins, saveing in two divffrent places, “My Documents” and on an external hard drive. Then I whent away for maybe 30 mins and when I got back I could no longer save on eather of those locations, it said that it could not find the address to that file. Ok fine so I tryed saveing the file with a diffrent name, same thing. Then Flash quit and I lost all my work.
