Online problem, any fix?

So I played a quick online game and a team match-up and it worked fine. However, whenever I enter the game now, it just says that connection to 2K server cannot be established and I can't even login.

What could be a problem? I haven't made any changes to system or game after I played those first matches.

Try reinstalling the patch, possibly?

I'll try it, thanks

Oh damn, it says my serial key is invalid now :/

Aw, dude, that really sucks. If you already made a 2K account I think you can skip straight to logging in, because the only time i had to put in my serial key was when I was registering for the first time.

It seems I can't skip it. This is what I get when I want to enter the game :



...and later it says that my serial key is incorrect.

I'm not sure what I can do here... I'm sorry, I hope you can get it fixed soon

It's ok, I appreciate your help.
