Wont load to game

I press play on the log in and it shades like its going to start the game but it just sits there. I click on it again and it brightens up like I never clicked it. Ive logged in with my log in info so I know it works. I havent played due to my last computer broke and had to wait to get a new tower ( yes it was some years ago). Its fully updated and ready to go if it would just let me load the game. What am I doing wrong?
