Does this happen as soon as you open the game, or only when trying to load a save file?
I think this is a system error and you may need to reinstall Tailor Tales completely. You can preserve your save data by copying these folders: Tailor Tales/www/save and Tailor Tales/www/data/img/pictures/Fashion/Completed. Copy these current folders and place them somewhere else as you reinstall the game. Once reinstalled, replace the new folders with the ones you copied. That should keep your save file intact as you reinstall the game.
