ITunes Not Responding When Syncing ITouch

After a recent software update I can no longer get the ITouch to sync with Itunes. If I attempt to sync when ITunes is not running it will begin the process and start to sync. However after getting part way through it stops updating and when you go to "force quit" it indicates that Itunes is not responding. If you try to sync when Itunes is running it immediately goes into a non-response mode and does not even try to sync. I have tried restarting the machine and performing disk repairs and have restarted the ITouch as well. Everything functioned well until the most recent software update. Any help or ideas would be appreciated.
