Itunes keeps locking up and giving me the error message "itunes was unable to load sync services" if I wait it will start working until I plug in my Iphone then it locks up for a while, once it starts working I try to sync my phone and that just keeps running ALL DAY! never finishes. This just started after the last Itunes update. I have uninstalled/reinstalled Itunes several times. Is it a Vista problem with Itunes? Should I upgrade to 7? Is there a fix? Am I the only one with this problem?
