title: UML diagram shapes missing on Visio 2013
body: <p>I have installed Visio 2013 Standard and I'm trying to create an UML diagram.</p>
  
  <p>I choose the "UML class" template but when it opens, the Shapes panel is empty. As recomended, I go to "More Shapes" menu, but cannot find anything related to UML.</p>
  
  <p>Have anyone had this problem and got a solution?</p>
  
  <p>Thanks</p>
