That means you probably played a more advanced version than the one you currently downloaded. Make sure to play only the highest number version of the game you currently have.
It says that my version is 0.2.2.0 but I dowloaded the Dress or Undress 1.3 relesed now and do not work :(
Then you should play version 0.2.2.0 or higher, not 0.1.3.0.
