Minecraft won't work for me?

I purchased and downloaded minecraft. When i go to open it, it says play so i click that. Once i click it something pops up that, stays mojang stay for a few moments, then disappears and puts the launcher screen back on. Is there somthing else i need to do. If no one knows is there a way i can contact mojang?
