title: Recovering Unsaved changes - Eclipse
body: <p>I unintentionally closed Eclipse withing saving a file as part of restarting the system. So I lost an entire day of work. I Googled for it and I found <a href="https://stackoverflow.com/questions/712505/help-recover-eclipse-file">this one</a>. For me, though it shows History of the files, when I select <em>Compare With > History</em> item, it shows <code>State is not valid or might have expired</code>. I am still hoping I have the history to recover, if I could find out how to bypass this error message. </p>
  
  <p>Can anyone help? </p>
