2 years of work should have backup copies. Not only on the cloud because as Wozniak noted at http://www.cnet.com/news/woz-the-cloud-is-a-nightmare/ you can't depend on that alone.
Apple OWNS this one. Get to the Apple Store or call apple support.
All I can write is that this is all about backup. Including your disaster plans.

I have an Apple IPad 3rd Generation. When I attemped to sign up for cloud somehow a typo occurred. My forbeingbest@msn.com ended up with a hyphen after the com. I cannot verify. Apple Security is giving me a security question I don't recognize and definitely can't answer. They tell me they will have to lose all my data to simply remove this typo. Can this be true? I need to start quick books for a new business. The loss of 2 years work is catastrophic. Is it possible to introduce another address for the cloud on the same IPad? How can I resolve this dilemma?
