Any idea iam using sql 2008

Well either delete the database that's conflicting with your backup and then restore it using the restore option of databases (right click databases and hit restore) | Make sure you check overwrite option while restoring the empty database.

yes i restore with this option but the same result maybe i should use sql 2012 or what

bro go to your SQL main place in :
c:\Program Files\Microsoft SQL Server\MSSQL10_50.Ace\MSSQL\DATA
and delete the data base you want to restore then do the same progress again !
