Noticed my calendar wasnt syncing to my iPhone 4 & noticed in iTunes that it says that Microsoft Outlook must be installed in order to sync calendars - and it is & it was syncing just fine until recently!

On top of that when syncing I get a message 'itunes was unable to load data class information from sync services. Reconnect or try again later.'

So I read somewhere that the latest version of Quick time should be installed (it wasnt) so I installed it & it made no difference.

Meanwhile my itunes wont launch immediately - its running in processes in the taskmanager, then it says 'not responding' & then finally launches some 5 minutes later!

Im not tech savy & my head is hurting!!!!!

PLEASE HELP ME!  I have removed & reinstalled itunes to no avail.
