title: Cannot open database.mdf after opening in Visual Studio 2012
body: <p>Ive been working on some stuff with Visual Studio 2008, and SQL 2008 aswell..
  Then i opened the project on another computer with 2012 version.</p>
  
  <p>And now when im trying to work with the files in 2008 again, i cant open my database.mdf, becouse the 2012 sql has upgraded my database file...</p>
  
  <p>Anything i can do to save it?
  (Btw. the data aint that important, but more the whole table setup and relations)</p>
