title: cannot open the file because the open options are incorrect
body: <p>Im using photoshop library in C# application.</p>
  
  <pre><code>public static ps.ApplicationClass app
  
   createPreviewThumbnail(filepath);//looks like "http://192.26.1.105/Connect/testjob/test.PSD"
  
    public static void createPreviewThumbnail(string sourcePath)
      {
       app = new ps.ApplicationClass();
       Photoshop.Document doc = app.Open(sourcePath, null, null);
        ......
      }
  </code></pre>
  
  <p>This code works fine but some times I get this Exception that <code>cannot open the file because the open options are incorrect</code> What may be the reasons for this?</p>
