New Tabtronics can open games or club penguin

[Tabtrouble]

Hi just joined the forum as we bought our son a Tabtronics to play club penguin and some other games. Angry birds seems to work but we bought monopoly and when he tries to run it says there is a server error. Also when he goes to the club penguin site it starts to open and then shuts the browser down.
new to all this , sorry if I've posted this in the wrong place. Any advice great fully received .
