The error message indicates that the OWL file is not a valid XML  
document.
 From the message text, it appears that there is either a missing  
start or
end tag, or some other problem that makes it appear that way.

The parser is complaining about finding a structure something like this:

  <a>
    <b>
    </a>

Where the A entity ends inside the enclosed B entity.

You will need to fix the OWL file so that it is a legal XML document.

Was the OWL file saved from Protégé?
