Notebooks (iPad 2) won't launch anymore!
I am a new user - I created a new book, created some notes. Then today I created a To-Do Item that has a custom link to another note in it.
After checking the To-do item off as complete (from the screen where I can see all of my To-do items in the book) the application closed.
Now the application won't open at all, I don't get any error messages.
I tried turning my iPad 2 off and on again, but that doesn't help
