Let me guess... you really bought a used copy, not a new copy, and you want an online code, so
A) you're going to ask people on the forums for an online code, or
B) you're going to email ND saying they gave you a code that doesn't work to see if they'll give you one.
Yes u'r right wise man. You are an ..... It's new, it's offical and it was sealed and I ask only how I can fix. Also u wrote proverb below about just yorself.
It's kind of ironic that you're giving me grammar lessons, yet you can't even spell "your," and "yourself." Not to mention you can't even put a few words together to form a sentence.
Want to know how to fix it? Buy a code from the PS Store. Out of the millions of brand new games that have been shipped with online codes, not once have I ever heard of anyone getting a faulty online code -- ever!
Quit the B.S.
I had the same problem as you did.
It turned out that the redeem code is region specific. I bought mine on Amazon, and it's north american version. However, I was trying to activate the online pass with my Japanese account, and it didn't work. I have an us account as well so I tried that and tadaaaaaaa!! Worked!!
Check your PSN account and it has to match the region of the sealed package you purchased.
Hope you can play MP, too. It's quite addictive.
