Any successful "syncs?" with BB DTM 6.0?

Has anyone had success with BB Desktop Mgr 6.0? Since I upgraded to it last month I cannot get a sync. Cannot sync with Yahoo period (calendar or contacts) without crashing, did successful sync with the "Windows Native Address Book (Vista), but it only picked up less than 30% of my Calendar entries. Outlook did ok on the Contacts but put in screwy &'s and +'s instead of some letters and numbers on certain contacts, and the Calendar was even worse (81 0f 112 entries picked up). So have anyone had success with the new DTM, or should I revert back to 5.0?

I haven't had any issues syncing DM 6 with Outlook 2003 with the usb cable as well as using BT.

Good Luck
