Fix it yourself

This issue can be caused by two things on your computer.  The above script corrects both issues.

1. The WSCommCntrData.xml file on your machine could be corrupt.  Your Revit product may hang when it is being read.   While your Revit product is closed, move or delete the WSCommCntrData.xml file at the location below:
   
   Windows XP
   C:\Documents and Settings\%username%\Local Settings\Application Data\Autodesk\Revit\<Autodesk Revit Version>\ENU\Components\WebServices\WSCommCntrData.xml
   
   Windows Vista & Windows 7
   C:\Users\%username%\Appdata\local\Autodesk\Revit\<Autodesk Revit Version>\ENU\Components\WebServices\WSCommCntrData.xml
   
   In order to see this file make sure that Windows Hidden folders are visible on your machine
