This is probably one of the best freeware tools I know for undeleting stuff and it has saved my hide so many times I can't tell you. Download it then just run it, its fairly easy - doesn't need installing so you can even run it off a floppy disk if you want (I'd save the original file to floppy first and expand it there so you don't run the risk of overwriting your file on the HDD) then see if you can recover! Best of luck!
