It sounds like you've lost them then.
The only thing to do now would be to uninstall the game, delete all of the folders and files except for Scripts\Playgrounds and Scripts\CreatureMind. Although your profiles are lost your creature isn't.
Then re-install B&W, apply the V1.20 patch and start a new profile. Once you've finished that blasted tutorial and get a creature, it's easy to swap him with your old creature if you wish to do so. Look under "Lost Creatures" in this FAQ.

You should also get in the habit of backing the game up using BWBackup
