Hey this is from someone else who had wrote a thread, he explained it better than me so maybe this would help,
"Picked up two copies this morning (PC and PS3), one for my account, one for wifes account. Tried to log in with my normal account using the launcher (PS3)....after several "server not responding" messages, it says I have no FFXIV game registered with the account and need to either download or register a new code. However, it doesn't give me any option to plug the numbers in. So I have to log in on the website (provided on the card). Updated my games with the code, so now my account has two active (the old one is the EA). Log in on the PS3 and get the same message, like there's no game registered with my account.
Tried the PC. Logged into my wifes account, updated her profile with the new serial code. Now she has two games, EA and the copy we just bought. Tried to log her in on the launcher and it wants me to plug in a new registration code that doesn't even match the format of the one in the box.....brick wall."
Please if anyone can help, i'm not really knowledgeable with computers, so i dont know if im missing something obvious or not ; ;
