how do you fix itunes error 10319

When I try to sync my iPad 2 on my hard driveI get the error message "10319" and the device will not sync. I created a new administrator user on my computer but the error persists with the new user. I tried manually syncing the iTunes categories (podcasts, photos, etc) sequentially to find what's causing the problem but the "cannot sync" error reappears almost as soon as I start. I've deleted the 3 iTunes preferences I found in my Library.I would like to delete and replace my iTunes app but I dont have my install discs available. I do have an iTunes app installed on other volumes. Would dragging that app into my hard drive applications folder install it in place of of my current iTunes app?
