Nokia :: N97 Security Module Error

N97.i had my first attempt to download a free game from Ovi shop.after i got the txt message and went to the link for the download, and download completed, the blue screen said something about how the games are specially chosen > OK or Exit , the system froze, i tried to click both ok and exit but nothing happened.

i did a power off and the power on, and then when i went to setting to find the game, i recieved a message that said Security MOdule Error.every time i tried anything, like checking contacts for damage, i go the same error message.i did another power off and power on and the error message stopped.i have uninstalled the game and because it was my first download like that, i am now shy to try again.what might i have done wrong and how could i make sure it doesn't happen again.
