You can see all the older versions under the development log. Might be worth a shot.

BTW, if you have any old save data, you could try deleting it? You can find it at C:\Users\YOURNAME\AppData\LocalLow\OmegaOzone\Dungeon Tail. That might work but let me know if it doesn't. Deleting the registry at HKEY_CURRENT_USER\Software\OmegaOzone\Dungeon Tail might also work.
