I downloaded a new game for the iPT, iTunes said there was an update for my iPT, do I downloaded that as well. After an hour of downloading, it started to install and gave the error 1604. I researched it and it said to try other usb ports, I did and same thing. After trying different usb ports and rebooting the computer, same results. I'm not using a dock, std Apple usb cable. I've updated this iPT with this computer before and had no problems, the iPT is about 6 weeks old now. I did however get a new computer, I noticed that when iTunes came up on this new computer (old HD, same install of XP with a new MB/Vid/CPU...) It asked me if I wanted to have this computer registered for use with my iTunes account, I said yes and have been using it and updating my iPT several times over the past few weeks. I thought it might be something with changing the computer, so I tired to install iTunes on my notebook and it came up with error Assembly microsoft VC80.CRT... So I'm upgrading Vista on that computer to see if iTunes will install there. I'd like to get the iPT working, anyone know what the 1604 error is? Is the update for iPT something that everyone was getting and did others fail? Any suggestions? thanks, KarlJay.
