After see the images I can see that both are of different options. One says "buy tokens" (first) and other "earn tokens" (second). For any reason when you click in bar to buy the tokens the windows option that open to you is the "earn tokens". Clean your browser cookies and cache and update you adobe flash and try again. If the problem remains try change you browser. Or try the login/play in facebook page. In last case, contact the support.
