Today when I went to work I saw the developer of this file had
updated the code and I noticed the tablename that was causing
my problem was removed. The statement was part of a
EXISTS or NOT EXISTS statement and when I quickly looked
at what was removed and replaced with, I believe the table that
was causing the problem was in the original SELECT statement
before the EXISTS or NOT EXISTS condition.
Anyhow I have kept the database and the problem as a copy
and if I do find the time in the near future I will try to troubleshoot
it further.

Very good idea I'll keep this mind to compare execution plans instead
of going through long graphical execution plans.
Thanks again.
