Problem with sync service in iTunes and iPad and iPhone

Hi there. I'm having problem with my iDevices and iTunes. Since I updated my iTunes to 11.1.0, it won't sync with either of iPad 4 or iPhone 4 that I have. Even before upgrading my devices to iOS 7. Here is the error that iTunes gives me:

"iTunes was unable to load data class information from Sync Services. Reconnect or try again later."

I tried to solve it by re-installing iTunes but it didn't work.

Mind you that it recognizes my iDevices but does't sync and it is installed on Windows 7.

Can anyone help? Thanks for your attention.

iPad, iOS 7, iPad 4 retina display wi-fi only

Hello Okarimi,

Thank you for using Apple Support Communities!

I found this article for you to help troubleshoot the issue named:

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

http://support.apple.com/kb/TS2690

1. Check that iTunes is up-to-date

Ensure that you have updated to the latest version of iTunes.

2. Reset Sync History

Resetting your Sync History is a simple step which may resolve some syncing issues. If this works, iTunes will prompt to Merge or Replace the information on your device when you next attempt to sync. To reset your Sync History:

Disconnect your device.

Open iTunes.

From the Edit menu, choose Preferences.

Click the Devices tab.

Click the Reset Sync History button, and then reconnect your device.

If this resolves the issue, and you know all of your contacts, calendars, bookmarks and notes are on your computer:

Reset the Sync History again using the steps above.

Select the device in iTunes and click the Info tab.

Scroll down to the Advanced section, and under "Replace information on this iPhone/iPad/iPod touch" select Contacts or Calendars.

Click Apply.

If the issue persists, and you know all your contacts, calendars, bookmarks and notes are on your iPhone, iPad, or iPod touch:

Remove all of the contact and calendar information from Outlook.

Select the device in iTunes and click the Info tab.

Scroll down to the Advanced section, and under "Replace information on this iPhone/iPad/iPod touch" make sure Contacts and Calendars are not selected.

Click Apply.

3. Unplug all optional USB devices

Unplug all USB devices from your computer except for your iOS device, keyboard, and mouse (if needed). Also, if your computer has a card reader, disconnect the card reader from the computer. If your computer has an internal card reader, open the Device Manager, and disable any "USB Mass Storage Device" entries associated with the card reader. Restart your computer and test.

There are more steps in the article, if neeed, but these will get you started.

Cheers,

Sterling

Thanks for the reply. Does reseting the sync history erase all the data including contacts from my iphone and ipad? I tried to backup them on the icloud but it just says "estimating time for backup".

I finally resolved my problem. I found out that my "Moblie Device Support" folder which was in Driver C; Program files(X86); Common Files; Apple(Note that I use windows 7) was empty and there was the exact folder which was

"Moblie Device Support" in the other drive on my laptop. I simply copied the data into the empty folder and reconnect my iDevices and the iTunes started to sync. Hope this helps to people who have the same problem.

I don't know whether this refers to an old version of iTunes, but there is no "reset sync history" in my devices tab. I've been unable to sync my iphone for several days. It just hangs. I was told to reset the sync history and I can't even do that! Apple, your software is getting worse and worse. What do I do now?

I'm having the same problem. I get an error message and my phone wont connect. When I try to go to preferences my iTunes just freezes whether my phone is connected to my computer or not. This is extremely irrating, especially since I am not tech savvy. Can someone please help me resolve this?
