I turned home sharing, however, when I push "Done" button, icon on the left hand side disappear

I turned home sharing, however, when I push "Done" button, home sharing icon on the left hand side disdappear. Also, it doesn't show my library.

I have Mac at home and I could successfully use home sharing on my laptop. Now I try to share I-tune library on Mac with this desk top computer. It might has different version. I recently updated I-tune and it looks different than the one I have in my laptop. It looks complicated so I didn't upgrade I-tune on my laptap computer.

I turned home sharing turn off and on to see if it makes different. But it is acting the same way. Please help.
