Itunes was unable to load provider data from sync services

I too had the "iTunes was unable to load provider data from Sync Services. Reconnect or try again later." problem with my devices today. Couldn't sync nor update.
In iTunes all my backups wasn't showing under devices, yet they were all fine showing in the folder system under /Library/Application Support/MobileSync/Backup/.
A couple of days ago I updated Xcode to IOS 4.3.1, I wonder if this was the problem too?
My solution was to download iTunes again and install it, without uninstalling the one that was already installed.
I then restarted the computer, and all my backups were again showing under devices in iTunes and I could again sync and update. 🙂
