I had similar issue when third party backups were interfering with MS SQL...
I recommend you first to apply latest Service pack and cumulative update for SQL Server 2005

I am trying to restore litespeed SQL2000 backup on SQL2005 using litespeed(actually this was a working procedure which fails recently).
