I don't have access to an iPAD2 so I don't know if the advice here on the forum regarding missing saved games will apply to that platform. (for example, does the iPAD run the game using a Flash Player or what?!)
All the same, have a look through the thread called "
Where are my Savegames?". It's a long thread but the link I just left you starts you from the beginning. See if you can tease out a fix from all the suggestions left there and then please come back and let us know what worked for you.
Good luck!
