Can't sync iPhone with iTunes 9.1 after update (Windows 7)

Hi,
after the succesfull update to iTunes 9.1 synching contacts, dates (Outlook 2007) and bookmarks (Safari 4.0.5) does not work anymore. I haven't had any sync problems before the update. All other app, music and videos gets synched well.
iTunes gives two error messages (translated from german, maybe it's an localzation problem?):

1) iTunes couldn't sync information with iphone since Synchronisation is not activated. Do you want to activate Synchronisation?
If you don't activate Synchronisation, itunes can't sync contacts, dates, bookmarks and email accounts to your iphone.
When i try to activate the following error message pops up:
iTunes couldn't access the provider data from sync services. Try again.

Comletely deinstalling and reinstalling of iTunes and ipod services didn't solve the problem.
Has anybody a similar problem or a tip for me? Should I go back to iTunes 9.0.3?
Thanks for any help.

PC, Windows 7, 32 bit

I had the same problem.
I would connect my iPhone 3GS running 4.0.1 to iTunes 9.2.1 on my MacBook. It would "verify iPhone" for a bit, then start syncing. It wouldn't get very far, however, until iTunes "unexpectedly quit" or whatever.

But I fixed it. Here's what I did.

I uninstalled iTunes using these directions: http://support.apple.com/kb/HT1224

After I restarted my computer I downloaded iTunes. The first time I tried to sync my phone it crashed again. But on the second time it worked
