Icons do not show up in Informatica Mapping Designer

I am new to Informatica and I am trying to learn it bit by bit.Currently I am able to enable the repository services but nothing works after I get connected. As in the transformation icons do not get highlighted when I open the mapping designer. Please find the attached screen-shot. Let me know if any questions. Thank you.

Solution

You opened the Mapping Designer and connected to a folder but there is no mapping loaded - create a new mapping or open an existing one and transformations toolbar will become active.
