all frames gone! please help!

I created a cut out character on for each layer I inluded more frames so I could draw other istances of the mouth, eyes, hands, etc… I saved this fila as “a diferent version” with a differnet name as I progressed on the design of the character. Now I opened it and all is showing in the timeline is frame one of all the character parts. Where did the other drawings went? I went into the “elements” folder and there are a bunch of files with names like: eyes_1 and eyes.31 is there a way I can restore all the drawings that I am missing now? THanks for the help!!
