I' ve uploaded, a flash file, then my pc crashed before i could back i up. i needed to do someediting so , i downloaded it- but i can't seem to be able to open it- it keeps coming up with the error message - can't open , file is locked.

Are you trying to open the flash file in Macromedia Flash MX? If so, you can't open a flash file created by someone else.
