calling Anerica isn't that expensive nowadays but why phone there?
You can ask the same question of Intuit in the UK - call them on:
0906 7550 550
but be warned - calls to this number cost 75 pence a minute.
Or you could write to them:
Intuit Service Centre
PO BOX 4944
The newest version of Quicken is QuickenXG by the way.
