TaskItem.Body and AppointmentItem.Body = access violation (NULL pt

[Kayako Inc.]

I am having a hard time figuring out why my add-in crashes Outlook 2000 and
XP but works on 2003 and 2007.

If I call TaskItem.PutBody (with any argument), or AppointmentItem.PutBody
(with any argument), I always get the stack trace below, resulting in a
access violation at a NULL pointer in OUTLLIB.DLL!GetCentralObject()

I _really_ need help here. I have no idea what to do. Please see the

OS is XP Professional SP2. I have tried this in all variations of Outlook
2000 and XP (w/ service packs, without). Code works fine in Outlook 2003 and
2007.
