Question for mac users

1

so i use flash all day at work and im busy working on this one site. anyway, i usually just leave all my apps running over night so i can just pick up where i left off the next day. so today i come to work and try to save a file (a very IMPORTANT, CRUCIAL flash file!!!) and i get an error that says something like “cant save file cause its past its end”. now i have no idea what that means so i try to save to my desktop… same thing. so then i try and save to the network drive… same thing. so i think for a bit and realize i didnt make many changes to it so i can close it and re-open it and redo the minor changes i wanted to save in the first place. only now my file is totally gone. the .swf still exists but the .fla is GONE!!! i have been working on this project for weeks and the file is the main shell for all the other .swfs that get loaded into it. i am so screwed now. so my question is does this happen to anyone else? god i hate macs now…
