Web Dynpro Content Administrator

Sorry for the lengthy questions - but all related to Web Dynrpo Content Administrator:

In the Web Dynpro Content Administrator, I have both Create JCo Destination and Maintain JCo Destinations button disabled. How can I make them abled? I have an Admin rights.

Also, when I test connection to the SLD nothing happens, but when I start the SLD button - the SLD opens up in another browser? What is the reason?

Finally, in the J2EE - Visual Administrator > SLD Data Supplier > when I test the CIMClient Test it fails - it says: Failed to generate and test CIMOMClient object.

Please help.....
