I´ve make backup and restore with FB 2.0, drop all table´s index an created
then again. But the problem goes on.

I can´t sent you the Database now because it´s a customer database but I´ll
try to delete all other tables and change some data in order to send then.
In a few days I hope to email you an url where you can download the DB

thanks

Try in 2.0 to backup & restore the database, after try to drop all indexes
and create again, test the query ( but do not force the old plan ).
If you have the same result, send me both databases to test, because I am
very curios about this problem ( if are big only with the required tables).
