title: Installation of objectaid in eclipse, no valid license was found
body: <p>I have followed the steps of this guide to install objectaid on eclipse GALILEO in ubuntu 10.10 :</p>
  
  <p><a href="http://www.objectaid.com/installation">http://www.objectaid.com/installation</a></p>
  
  <p>But after the installation I get this message in console:</p>
  
  <p><em>ObjectAid Sequence Diagram is not available because no valid license was found.</em></p>
  
  <p>I suppose it's because is possible to buy also the non-free version.
  I would try the evaluation version, how to do this?</p>
