I know some people struggle to play Schockwave games, so I decided to help!
To make Shockwave games work on you computer, you have to uninstall any previous Shockwaves versions you have and Install (you need an account to see links).
After that, go to your Internet Explorer, and search for the menu. To open the menu, you have to click on the gear icon oh the top right. On the menu, you must add "neopets.com" on the compatibility settings:
Then, you should select Internet Options, click on "Security" and uncheck the "Enable Protected Mode":
Now you should be allowed to play Shockwave games!
