I've just tried the method described in that post but the unit is still unresponsive.
Out of curiousity, does your story crash/freeze often?
I'm wondering if I've just had the bad luck of receiving a dodgy unit...
EDIT:
Whaddaya know... I left the story connected to the pc while checking the return policy for the retailer and out of the corner of my saw the screen change... the damned thing has now accepted a standard reset and is working again! GRRRRR!
