Photoshop Meltdown :(

[Corby]

Hello,

I was working on a great background in photoshop, when I pressed crtl-s to save. Photoshop froze up and I had to reset my computer. When I booted back up, the old psd was now a .tmp file and wouldn't be reconized by photoshop. Can anyone download this file and try to restore it if such a thing is possible? Here's the link:

Also, I just installed new memory to my computer. Could this have been why photoshop failed?
Thanks!
