Nike.eu Website Issues

Hi,

I am from UK can anyone help me? I cannot login to Nike.eu nor can i add anything to my basket when i do it keeps spinning, this happens when i use my home broadband connection that is what i use majority of the time, but when i try to access this at work or use my mobile internet on my mac then i dont have any issues on the website. Do you guys think that they have banned me? I seriously dont know whats going on, if anyone can help id really appreciate it...
