I regularly use iSync to check for updates and found that Quicktime 6.5 was available. So, I downloaded and started to install it. Got to the screen where it required a serial number to continue HOWEVER on the same page it states if you don't have a serial number don't worry just continue. I tried but I keep getting a popup screen saying that the number is incorrect. Any help on this??? BTW, running a G5 1.6 w/ Panther 10.3.2. Thanks
