  <p>I have tried restoring using 2012, 2008 and even 2005 but nothing works, I have used the following query and through the Tasks>> back up but nothing works, here's my SQL:</p>
  
  <pre><code>RESTORE DATABASE JA FROM DISK='c:\glyn\JA.bak'
  </code></pre>
  
  <p>Does anyone have any suggestions? I've read that the bak could be corrupt, it was sent to my by another developer on DVD who is working on the project.</p>
