I get the error "unable to load data class info from sync services" and eventully itunes freezes. will this article help me?

Hello there brigidfromca.
Messages can always be pretty daunting when we're not sure where to start. I was able to locate the following Knowledge Base article that discusses the very message you're getting:
iTunes for Windows: "Unable to load data class" or "Unable to load provider data" sync services alert
http://support.apple.com/kb/TS2690
It is a pretty thorough document with multiple steps to review, but looks to be great place to start for a resolution for you.
Thanks for using Apple Support Communities to reach out to us for answers.
Cheers,

Hey, when I connect either my ipod or ipad to itunes I get the prompt 'itunes was unable to load data class information from sync services. Reconnect or try again later. Can anyone help me with syncing my devices?? Thanks in advance

I am having the same issue, anyone else ?

Was unable to load data class info from sync services. try again later.

Since installing the latest version of itunes (11.1.5.5) whenever I have either mine or my wife's iphones (4 and 5c, both with the latest 7.1.1) turned on and I start iTunes, I receive the error message saying that itunes was unable to load data class info from sync services. try again later.
If I leave the phones turned off and open iTunes, I am able to sync my old ipod so it appears to be an issue with the software on the phones?
I'm just not sure where to start. I've made sure that itunes has the latest version and no more updates are available.
Thanks in advance,

this is on a windows 7 machine, btw.

I tried to sync my phone and received this message: "iTunes was unable to load data class info from sync services. Reconnect or try again later." Now it doesn't sync calendars because it says I need to download Outlook, which I already have

I have synced my phone to my computer several times. This time i received this message: "iTunes was unable to load data class infor from sync services. Reconnect or try again later." It says if I want to sync calendar I must install Outlook to my computer?? Why does iTunes not recongnize that I already have Outlook installed on my computer?

This worked for me...i did a restore on my computer to take it to a date prior to the last update i did on itunes and now it works just fine. Everytime i do a backup it syncs my Outlook! When a request comes up saying there's a new version of itunes click here to download the latest one DON'T do it.
Here's how to do a restore on your computer:
Create a restore point
A restore point is a representation of a stored state of your computer's system files. You can use a restore point to restore your computer's system files to an earlier point in time. Restore points are automatically created by System Restore weekly and when System Restore detects the beginning of a change to your computer, such as when you install a program or a driver.
System image backups stored on hard disks can also be used for System Restore, just like the restore points created by system protection. Even though system image backups contain both your system files and personal data, your data files won't be affected by System Restore. For more information about system images, see What is a system image? You can create a restore point manually at any time by following the steps below.
Go to the Windows website to watch the video. (1:08)
Click to open System.
In the left pane, click System protection. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
Click the System Protection tab, and then click Create.
In the System Protection dialog box, type a description, and then click Create.
For more information about System Restore, see What is System Restore?
I HOPE THIS WORKS!

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?
