The database 'D:\Myproj\APP_DATA\ASPNETDB.MDF' cannot be opened because it is version 661. This server supports version 612 and earlier. A downgrade path is not supported. Cannot open user default database. Login failed. Login failed for user 'Sparrow-VAIO\Sparrow'.

looks like you need to install the 2008 R2 version of SQL (or Express). heres the link

EDIT: looks like the server explorer in VS 2008 isnt up to par with the databse file tha you have. is moving to VS 2010 is an option ? if not you can attach the database file to the R2 instance you have installed and access the database using a standard connection string.
