The initial 120 codes from series one have been depreciated, and the new Season two codes are active. However in a change the codes for each episode of season two are only active until the next episode is aired. This will be typically 7 to 10 days after the prior episode.
It is believed this only time-frame applies from the first US air date, the first code was released as a screen overlay when broadcast on the Syfy channel, it is unknown at this time if codes will be re-activated then the show is broadcast in other regions or these are just one time codes.
