title: error when running any query in sql server management studio: the file exists
body: <p>When I run any query in sql server management studio, I get the following error:</p>
  
  <blockquote>
    <p>An error occurred while executing batch. Error message is: The file exists.</p>
  </blockquote>
  
  <p>Restarting SSMS didn't help. Neither did rebooting the machine. The only thing I found on Google was someone saying "report the bug to microsoft" :P</p>
