The message says that database is for a later version of SQL Server (661, which might be SQL Server 2008, or 2008 R2), but you can only use version 611 or earlier.

Either install a later version of SQL Server, or get a file that is compatible with SQL Server 2005.

Alternatively, at backup time alter the compatability level of the database, i think that should also work.

Altering the compatablity level will not let you restore to a previous version of the database server.

Sorry ill-informed comment!
