Hi, dunno if this is just me but I signed up for the 14 day trials at that website but the 'information' email that supposedly has the trial key on it still has not come. I made sure that the email address I put in was correct.
Far as I can recall the trail-codes are issueed by the website you visited when you applied for it.
I would assume that NCsoft granted them a stack of trail-codes. Even then if they ran out it would be their job to get a new stack of trail-codes from NCsoft and maybe even update their website when and if the promotion has been closed.
Attempted to create one yesterday...didn't worked! Seems Trial is facing a problem or they are out of Trial-stock codes. Really dissapointing cause at least they could inform the customers the existance of a "limited number" or something.
