Very strange 'restore previous versions' problem

Hi guys
about 2 months ago whilst on holidays i accidently copied over some photos ('copy and replace'. I've read up how to restore these files but there are 'no previous versions'.

The problem isn't that previous versions' isn't on or working at all as it works for all of my other files.. I can see them thumbnail of the photos that have been copied over, and when i click to open them in windows photo viewer, the photo appears (blurred as if loading) and then loads the newer version.

These are very important photos and i can't seem too get them back,

any help would be immensely appreciated i would love to have these photos back !

bump,

anyone?

Try this:
Restore Previous Versions of Deleted Pictures on Your Computer

1. Pull up the Start Menu and select "Computer" to locate the folder that contained the picture files you want to recover. Be sure that it is the folder where the files were actually saved, rather than a library.
2. Right-click on the designated folder and, in the pop-up menu, select "Restore previous versions." If your files were in a folder located in a drive, such as C:\, then select "Restore previous versions" by right clicking on that particular drive.
3. Review the list of previous versions of the folder or files within this folder/drive. Determine the most recent previous version of the picture files, or the folder containing them, that you want to restore and double-click on it.
4. Move the deleted picture files or folder containing them to a new location on your computer, by clicking and dragging them to that location in the access menu on the left side of the "Computer" window. Ideal locations for the new save might be a new folder, the desktop or an external hard drive.

perhaps i misunderstood what to do but that didnt seem to work..
