database query external exception error

i get an EXTERNAL EXCEPTION C000001D when i try to do an sql query on my
computer at work.  it works fine at home, although i was using an alias
at home.  i took out the alias from the object inspector and manually
gave it a path the the database file.  this is because i had problems
using an alias on another computer with my program.  is there a special
trick to getting a sql query to work on another computer?  i can only
get it to work on the computer (at home) where i compiled it.

please reply by e-mail and post
