Question regarding 2ksports.com

How can I upload my replay in game(NBA2k11) to 2ksports.com?! I have a 2ksporsts.com, but do I need to Log in first my account before starting the game to save My replay? Because I can't upload it, everytime I click the "upload to 2ksports" It said that I must go online. What should I do?

Hook up to PSN or XBL i'm not sure for pc though

if you are on PC you gotta goto the online menu and register to get online

then you upload

then goto community.2ksports.com and link your PC account
