Every time I click play it just starts the launcher over and never does start the game.
Try verifying game cache files. I had the same problem and it solved it for me. If you're using steam:
1. Load Steam
2. From the Library section, right-click on the game and select Properties from the menu.
3. Select the Local files tab and click the Verify integrity of game cache... button.
4. Steam will verify the game's files - this process may take several minutes.
5. Once the process is completed, the Check Window will automatically exit.
