Problem connecting with 2k Sports server

I just brought the game via steam and I some way can't connect with 2K Sports server. The Steam gives me a serial number for the game but they never ask for the serial when I start the game.

Servers are down right now, atleast for me... Try in a couple of hours...

Oh ok thanks

No problem!

Now I can connect. Other thing, where I can download the new shoes (like lebron 9, etc) ?

It downloads automatically...
