Gaia Shop My Gallery

Ok I am quite annoyed right now.

I was working on a commission for three days straight that has four people in it, FOUR, and it was getting very close to done. I was very careful to always save it.
Now the last time I closed Photoshop it was being a bitch (but I had already saved the file) and so I waited and waited, but gave up and turned the power off (it's a laptop).
When I came back into Photoshop the worst thing happened.... The file became corrupt! I am so pissed off actually that I want to destroy the computer. I think I may have found the backup file that the computer makes but I have tried and tried and it just isn't opening in any way. Grrrrr!
