ipad3 with iOS7 won't sync with iTunes

[Happyjap]

I am frustrated beyond belief, my ipad3 freezes at step 5of5 and just stays until I unplug with half my music and apps not loaded.

I have tried everything I can think of,clean install (x3) unchecking things and rechecking. I have my life on this ipad and have now been trying to sort it to no avail for 3 days, I'm desperate now and close to smashing iPad against the wall. Can anyone PLEASE help me?

Have you installed iTunes 11.1? It is necessary to sync any device running iOS 7.
