Problem with contact form 7

Hi there! I own the website http://www.learnincyprus.com. On Friday evening I have tried to install the “Another Classified Plugin for WordPress” and after that all my problems started. Anyway I reinstalled the contact form 7, the contact form extend to db, the fast secure form plugins. Now they seem that they work but I cant see them on my dashboard. I have tried to customize dashboard from the top right but I didnt manage to do it. Does anybody have an idea why the contact options left from the dashboard and how can I get them back. Thank you very much for reading my problem.
