Cannot Access My Contacts

After being forced to switch to Outlook Express, I am no longer able to get to my Contacts. Somewhere, it said that I need to go to my "Settings," but I cannot locate any way to get into it. Can somebody help me? Thank you.

Okay, they list similar questions on the right, and I found out how to access my contacts through the "People" ap. But I cannot add people to the different groups that I have, because the different groups aren't listed.
