In Contribute CS4, the menu items and the other items in the toolbar will be
enabled only when those options are supported by the blog servers.
Go to Contribute-> My Connection, Select the blog server and click Configure
button. You can see the blog server configuration dialog opened.
Click on Update Support button to get the latest support information.
In the above list box you can see all the supported items with green tick
mark. So need for re-installation.
Thanks.
