navision 3.60 restore on sqlserver 2000

Hi! I have navision 3.60 on its own database running. I have a sqlserver 2000 for testing. I made in Navision a backup of my whole database. Then I started on sqlserver 2000 my navision sql client , made a new sqlserver database and started then the navision restore. after some hours I get the following error message: ‘the sql server object nav.dbo.session (SQL) which relates to table session (SQL) is not there’. what can I do? Thanks for ideas!
