Yes, I have Eset Smart Security.


But nothing of these informations helped me.


I uninstalled now iTunes completely and installed it again.


Unfortunately now the following note comes up, when I plugin the iPhone

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


("iTunes konnte keine Datenklasseninformationen von „Sync-Dienste" laden. Verbinden Sie sich erneut oder versuchen Sie es später.")


...I think I hate iTunes :-(

By any chance are you running any Eset security software products (like Nod32) on that PC?


If so, there's a couple of alternatives.


Either try the procedure in Samoreen's post:


Re: iTunes 11.1.4.62 freezes while syncing with Outlook


Or, see if you can get hold of the Eset beta addressing the problem. As Samoreen notes in another post:


ESET have a workaround for this issue. They gave me access to a test version of the HIPS module and this fixed the problem. So I could re-enable the ESET_OPTIONS environment variable (although I still consider that it's a questionable idea). I upgraded to iTunes 11.1.5.5 and there was no problem.


So maybe you should get in touch with ESET support and request the new module ? Just send a message to Marcos in the ESET forum.
