On Android, When you try to install the book 2 patch it comes up with an error something along the lines of package invalid.  If you uninstall book 1, book 2 installs correctly but it won't let me play it, as it says I need to play book 1.

If I patch the book 2 app with the book 1 app then it just overwrites and the game once again stops at the end of book 1.

Help?
