This is something I've done before - and between 32 and 64 bit java's
Can you move a database within the same machine, windows->windows?
Which version of TDB?
What is the query and what does "no results" mean - zero rows, or rows
in the results with no elements? The latte is a sign of failing to shut
the database down before copying. You can't copy a database when the
JVM that created or opened it is still running.
