I've looked thru a lot of posts here but don't seem to be able to pick out one that will help me update my ipad 2. I keep getting the 3194 msg. I am on a PC that was only recently fixed itself, after about 10 months of being behind in updates. Now it's back from the shop, and I updated itunes, and tried to update my ipad, but am stuck at the error. Can anyone help?
