title: Directory not found in Pycharm when running code
body: <p>I get an error by running my code in pycharm. I get this  message : </p>
  
  <blockquote>
    <p>C:\Python27\python.exe: can't open file
    'C:/Users/Melinda/PycharmProjects/untitled/classParticipant.py':
    [Errno 2] No such file or directory</p>
  </blockquote>
  
  <p>Process finished with exit code 2
  I understand that I don't have the Folder named untitled, because I have renamed  it afterwards as Lab4.<a href="http://i.stack.imgur.com/E4KIr.png" rel="nofollow">enter image description here</a></p>
