[AccessD] Jumpdrive encrypted volume

Anyone here using one of these?  I have a 256mb model that I have been using
for weeks.  It was working this morning.  Turned off my laptop, removed the
drive.  This evening, I cannot mount the encrypted volume.  Win2K says
simply cannot mount drive (after entering password).  XP does a page fault
and offers to send a report to MS.

Any words of wisdom?
