Everytime i plug my iPhone in to sync since the update it says that iTunes was unable to load data class information from sync services. Reconnect or try again later. Why is this happening?

I just want to know what the problem is that is making my phone unable to sync to my computer. It tries to verify my phone but then that message pops up on screen and it freezes itunes. HELP

iTunes for Windows: "Unable to load data class" or "Unable to load provider data" sync services alert

When I attempt to sych with I tunes I get the following Error Message. "Itunes was unable to load data class information from synch services. Reconnect or try again later." How do I fix this? This started happening after I updated to the latest version

When I attmpt to synch my Iphone I get the following error message. "Itunes was unable to load data class informationfrom synch services. Reconnect or try again later. This started after I uddated to the latest version of Itunes. What should I do?

My iPods are working fine...this is just on our iPhone 3GSs....friend said his iPhone 4 was working fine with upgrade.
Tried: the winsock reset, uninstall/re-install of iTunes, shut the firewall down. Even called Apple...and after 2 hours of being told that "I'm savvy and have done everything they'd recommend" still with no fix...
Still: Takes over 2 minutes (not hooked up to phone) to open Edit-Preferences-Device...and can't find any backups?!?! Takes over 2 minutes to even open the phone to change spps, musice, books, etc....but won't let me do anything with contacts...wonder if this is what that error message is about (because I don't actually sync to an email program, I've just kept it all on the phone - mistake).

ITunes was unable to load data class information from Sync Services. Reconnect or try again later AND Your iPhone has never been backed up to this computer AND always Not Responding

First: I get the message telling me that "iTunes was unable to load data class information from Sync Services. Reconnect or try again later."
Second: In the Summary Tab under Backups, iTunes is telling me that my iPhone has never been backed up to my computer - which is not true. It's also telling me that my iPhone has never been backed up to iCloud. Again, not true. Although my backups are all missing from iTunes, I can see what I think is them in their folder: C:\Users\*your user name here*\AppData\Roaming\Apple Computer\MobileSync.
Third: iTunes is SLOOOOOOOOW. It takes nearly ten minutes - sometimes more - to launch, and when it does, it's constantly not responding. It seems every time I touch something it stops responding.
Fourth: I've been searching this "help" forum for a solution, and I've seen many other references, yet the only suggestion I've seen from someone from Apple is a reference to a solution that is over 2 years old - and DOESN'T WORK for anyone I can see who's tried it!
I've tried everything I could think of, and that others have suggested, including:
Uninstalling and re-installing iTunes
Ensuring I have the latest version of iTunes
Re-setting sync history
Renaming my Backup folder at the path above, and letting iTunes create a new one
Running around the house whilst pulling my hair and yelling obscenities
None helped. At all.
Hmmm... Been a devoted Apple/iOS guy for years, but maybe it's time to switch to Android?

I've resolved the issue with iTunes constantly not responding. It's a bit embarrassing. I had a DVD in the drive that was corrupt, and once I was able to remove it - BAM - iTunes ran perfectly.
I'm still getting the Sync Services message, and my backups are still not showing in iTunes.
Getting there.... I hope!

ITunes was unable to load data class information from Sync Services Issue

Hi,
Whenever I connect my iPhone 5 to my laptop (running Windows 7) I get 'iTunes was unable to load data class information from Sync Services. Reconnect or try again later'.
Now I've had a look at all of the various Apple troubleshooting advice (and many threads on the discussion boards) for this and none of it works. I've also spent the best part of three hours tonight trying to remove iTunes completely off of my laptop using various programmes to try and remove all the little bits it leaves behind, but again to no avail.
I've been having this issue for quite a while now and it first started occuring with my iPhone 4, so when the same issue occured with my 5, I figured it was an iTunes issue or something related instead of just a phone error.
I decided that I wanted to sort it now as the last two iPhone software updates have errored and I've had to restore my phone and the back-ups have failed on both occasions so it's becomming quite a tiresome process now.
Any other suggestions would be really useful as I'm starting to think I'm just going to have to start over with my laptop, which I'd rather not do as that would take forever!
Cheers

Sorry, I should have also said that I'm running the most recent iTunes software and that I can still actually sync my phone with iTunes.

The article says that I should upgrade to the latest iTunes. I am on the latest iTunes version.
If you could read just a tiny little bit further, under the "Additional Information" section immediately after that, it says:
If you are still experiencing this issue when syncing, or have not installed Xcode 4 and get this alert:
Follow the troubleshooting steps in Mac OS X v10.5, v10.6: Resetting the SyncServices folder.
If the issue is still unresolved, follow steps in Sync Services: Advanced troubleshooting for contact and calendar syncing.
Have you tried those measures?
