Restore Failed for Server: SQL Express 2005

I am moving my data base from one computer to a new one. I placed the .bak file in the backup folder on the new computer (Windows Vista). I keep getting these errors I have checked the security settings and my user account has full privledges. I added my windows login to the SQL Administrators as well.

Here is the error msg.:  TITLE: Microsoft SQL Server Management Studio Express
