title: Error detected when opening a Mathematica file
body: <p>In the last time when I wanted to save my Mathematica file, something was strange. Now when I want to open my file, it take too long and at the end just I see a few data and also I can not use that.</p>
  <p>I have uploaded my file here:</p>
  <p><a href="http://www.mediafire.com/?4etrrd3rauq0j59" rel="nofollow noreferrer">http://www.mediafire.com/?4etrrd3rauq0j59</a></p>
  <p>Could you please open that file and explain to me how did you do that and send to me again?</p>
  <p>This message appears in Mathematica after long time:</p>
  <blockquote>
  <p>There appears to be an error in the file named below. You should close it without saving, then check the &quot;Parse and load entire notebook into memory upon opening&quot; checkbox in the Notebook Options dialog. File name: D:\App\Math\Unt.nb.</p>
