Middle one (MMORPG) doesn't seem to be working I type in the code but main menu still shows that bonus is still available.. so I try again and still the same thing

Mine was a bit wonkey too i just ried again after a few hours and it worked.

2 people from similar IP addresses (such as 2 people on the same ISP) cannot get that bonus in any 24 hour period. You will need to use a web proxy, or a different ISP, or use your mobile connection, etc, something different.
