Restoring database in SQL server 2005 Beta 2

Hi guys,
I have a problem with restoring database in SQL server 2005 Beta 2:

Restore failed for Server '[ZEDNIK\TELBILL]'. (Microsoft.SqlServer.Smo)
-
For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft SQL Server&ProdVer=9.00.852.00&EvtSrc=Microsoft.SqlServer.Management.Smo.ExceptionTemplates.FailedOperationExceptionText&EvtID=Restore+Server&LinkId=20476
-
=============================================

System.Data.SqlClient.SqlError: The backed-up database has on-disk structure version 611. The server supports version 587 and cannot restore or upgrade this database. (Microsoft.SqlServer.Smo)

I have searched for some patches or something, but I haven't found anything.
Please if some of you know how to solve this problem, HELP!!!

Thanks,

Tomas

where did you obtain this database backup from? Was it from a later version of SQL Server 2005? If so, I don't think you can restore a database backup to an earlier beta version of SQL 2005.

What you need to do is upgrade you version of SQL Server to the version that created the db backup, then your restore should work.
