"An Error Occurred Opening This File" Issue

[lilya10679060]

So, I was animating something the other day. It was almost done, and it took me a long time to make. The next day, I get this issue (Image below). I don't know what I should do, I've already copied and renamed the file and there's still room in the file (Also pictured below). Please help.

if you have auto-recovery enabled, look for a back-up.

or rename the fla to zip > use winrar to repair > rename the repaired rar to a fla and see if you can open.
