Hi and welcome to EB:
Take a look at
this BlackBerry Support Document #KB14818. It looks like you have a contact with either invalid information in a field or possibly corrupt data. Although Vista is not mentioned, the symptom and message match.
Does it stall at the same point each time? You might be able to narrow it down if you can see what contact it is hanging up on.
I hope this is of help. Please visit and post often and let us know how you make out with this issue....
