So far as I know, unless the file was either:
b)stored on a Server running Windows Server 2003
c)duplicated earlier for some reason
then you're likely out of luck (I may be wrong - wait for others to reply as they may know a way)
With regard to c), think about where there may be another copy of the image. Did you upload it to a wbsite, or e-mail it to a friend? Also, Photopro may have cached the image when you opened it; run a search in C:\Documents and Settings for all image files. You may get lucky and find it there (be sure to enable searching hidden and system folders first, though)
