Hi - can you help?

I connect my phone to my pc and try to send a text message.
I click the icon 'send text messages' and the correct window opens.
I then click 'To' to chose recipients.

In the contacts list, I see names and number to chose from.
The trouble is, these numbers are old and not the ones I see
when I browse the contacts list on the phone.

To try and sort the problem I click 'refresh' and the it
syncs the phone and a new windows nokia.wab address book
I set up a little earlier.

When I look in the nokia.wab - the correct numbers are listed.
So if they are right in the address book and they are right when
I view the contact list on the phone, where are these old numbers
being stored and why don't they update?

Thanks if you can help,
and thanks for reading if you can't!
