Help! LG Viewty PC suite - PC Sync

Someone please help! I can do everything with my LG Viewty PC suite except syncronise my calendar and contacts with outlook.
It starts the process but then it stops almost straight away and says error message 'invalid class string'

then stops the process and says in the log report......

Contacts : Synchronise ( MS Outlook )

Initialize connection with MS Outlook (I)

Calendars : Synchronise ( MS Outlook )

Initialize connection with MS Outlook (I)

Synchronisation failed.

Fail to connect to the phone,
Please check the COM port and connect in idle screen.

Can anyone advise on why I cannot get any further with this? I am using windows XP..

Thanks!
