Hi jb,
If you're able to "Save As", then select that, and then select the save location as your Desktop.
The save folder for this game will be a sub folder inside Documents. So open that sub folder, and then drag and drop the save file from the desktop into the sub folder, where all the other saves for this game are.
Exit all folders, start up the game as usual and load the new save.
Any problems, let us know!
