XP with SP3 as OS. iPad with version 4.3 installed. iTunes latest release. Have already tried all of the web based answers to the following error message which pops up after about 10 minutes of the download of the new iPad version. "There was a problem download the software for the iPad......The network connection has time out etc.". I have already disable Norton virus and firewall. Have removed and re-installed iTunes. None of the these solved the problem. Can someone please suggest another set of actions to take? Thanks.
