It is not a problem with your program. The update servers were down (some of them) yesterday generating errors and today everyone updating at once (again) is overloading the servers again and that is why you may continue to get errors for bit until is slows down. Just wait and try again later, it will eventually get the updates. So don't get alarmed just because of this happening right now.
Meanwhile, check with that above thread - I've already replied a number of times in it. This one I'll close so we don't have multiple topics going on the same subject.
