What is the OS on tour computer? If it's OSX you need to update it and you have to do the search for it manually. It happened to me. Only after the update I succeeded updating to IOS5.
I've been trying for 3 days to update my ipad 1 i get the same error message, cannot back up continue or lose everything, i've been so frustrated i've been tempted to click continue and lose everything just to get it sorted, as half my apps have updates that i cannot download as i dont have the new IOS5, so annoying, i've tried everything thats been advised here and nothing is working
