title: My visual studio templates dialog box is empty. i can't add any form or file
body: <p>In visual studio 2008, when you want to add a new form to a winForms application, you right lick your project or project subfolder, then point to Add, then click New Item and then select the type of item you want to add. (New windows From, New Class, TextFile, Xml File, ...,).</p>
  
  <p>Now in my projects, the Add New Item dialogue is completely empty, so i can't add any thing to my project. The Project still compiles without any errors. This just happened suddenly. </p>
  
  <p>Am not sure what i might have done wrong.</p>
