I don't know how to track down the cause of this problem so I'll just tell you what's happening. I've gone through 3 iPods since getting this computer with Win 7 installed on it. Itunes will want to update the ipod software, and during the update will say there are errors and it can not update the ipod, leaving it useless, and for whatever reason it can't go back to back ups. Up until now I let it go because both ipods were old, this one isn't. My laptop is running XP, so out of frustration I tried to use that computer, and had no problem with it, but the laptop is old and probably on its way out. The error has something to do with tcp/ip. I use ZA Extreme security on both computers. Does anyone have any ideas, besides getting rid of the ZA, its not going to happen. Thanks for any help.
