As a Bethesda community manager helpfully points out, your old save files will only show up if there are new saves (GOTY) present -- if you only have old saves, start a new game and, you know, save. If you have in excess of 130 save files (a sign of prudence!), you'll have to delete older ones in order for the new ones to be displayed. Oh, and one more thing: "If your saves are taking a long time to load you might want to resave them and back up or remove the old ones."
And now we've exhausted our supply of the word "save," save for one which we were keeping for the en ... dammit, we wasted it!
