. . . the Windows key (the one on the bottom row of the keyboard with 4 little white way squares on it) and press F. This will enter the disc search routine. You'll have to work out for yourself how to use it - I can't advise you because I don't know what operating system you've got.When you've worked it out, ask it to search for a file named "SAVE000.MM6" (without the quotes). When the file is found, write down the path and the name of the directory it is in. Like I say, write it down, don't rely on your memory.
That is the name of the autosave file. All your other saves will be with it in the same directory.
HTH!
