Finaly it works in Argentina. In my experience, this is not the first time that Apple updates fails: ipdods no longer synchronize, airports extreme that become invisible , etc. My simple advice is do not despair, do not panic and wait. The customized solutions are always more complex than sit back and wait. In addition, we have to protest strongly at the forum to launch the solution process.
Think about this for the next time it happens. Be sure that it will happen again.
