How i install MGS Key in Games?

i have some MGS games and Keys , but when i put in the Game registration the Keynumber nothing happend , i try all switches on Handy but works not :-(

Um... I think in mgs, you cannot play their games or some options of the game are missing if you dont have the key. So if the demo caption aint there anymore, then you entered the key already.

i wrote
I HAVE THE KEYS

but the works not (im still in Demo modus)

WHY?

i wrote in the Key Number (in game) but than...?????????

nothing happens :-( no full version

so you shure that the Keys works?or what i make wrong?

and what i have to do when i wrote in the Keys?
restart handy? which gropes must I then press?
