It might be a glitch! If so you can contact dell support, or your computer might be an older type if so the game might not be able to register your computer :) Have a nice day or night.

The game stops loading for chrome users, this issue is because of the slow Chromebook. Chromebooks aren't made for games (even though they say they are) the Chromebook cant load past the starting screen due to complications through the system. Any other type of computer should do it for you though :) like a dell or a Mac!
