Whatsapp problem in Itunes 11

[Bash7]

So I have the whatsapp application on my iPod touch 4g, but today when i wanted to rearrange my apps' order through itunes, it gave me an error. It tells me that i need to authorize my device which I didn and it tells me that it is already authorized yet it asks again for authorization or else the app will be deleted. I*****here was your problem*****

Also, i'm looking to move over to iOS 6, is there anyway i can keep my whatsapp conversations after i update?
