title: Error updating changes svn
body: <p>I have PHPStorm installed and i open a directory containing a PHP project with SVN. Under the SVN tab in the Changes i encounter the following error:</p>
  
  <pre><code>Error updating changes: svn: E155021: The client is too old to work with the working copy at "..." (format 31). 
  </code></pre>
  
  <p>Some ideas? I have TortoiseSVN 1.7.7 installed, when i open the project the first time everything worked great, but on further opening the above error appear.</p>
