What happened to my Contact List? All my contacts disappeared after doing the last update. I can still get into the "People" page but there are no contacts there anymore?

I did an update a few days ago.  When I went to the "People" page in the Contact List I could get into the page, but the page erased all my contacts.  I can't even put in new or old contacts.  The only thing on the page is the 4 apps, Facebook, Twitter, etc.  I don't use any of those.  The page also has the 4 apps off to the left of the page and partically cut off.  I can't see anywhere that I can get the page to the other side where they were before.  Ever since the Contact List was changed to the "People" page things have gotten slower with the poor design of the "People" page.  I want my contacts back!
