Downloading Saved Games

I was playing Final Fantasy Three a few weeks ago. I wanted to continue with my saved game today and noticed it vanished from my computer's hard drive. So I attempted to download someone else's saved game from the website http://www.zophar.net/savestates/sne...fantasy-3.html but it doesn't seem to work when I load it up. It just says Error and Bad Checksum and all sorts of bad stuff when loaded up on Snes 9x and Zsnes does the same thing. I'm using version 1.5.2 of Snes 9x. Help would be appreciated.
