Get a FREE Dora The Explorer Game Today When You Register for Updates about Nickelodeon Video Downloads and Other Nick Jr. Offers! I signed up yesterday and Aidan loves it! He actually won’t even let me help him or check it out myself, but it really has kept him interested! It is regularly $19.99 so Free is a great deal! After you sign up and download, give it a few minutes otherwise you get a message when you open the game asking you for a product key. Once I waited about 10 minutes, and then loaded the game it worked fine and has ever since. Oh and this is not an online game, you actually download it onto your computer.
