Added (1). I actually just checked and I'm using the administrator account. Thats wrong… Why I wonder? I tried using safe mode but still won't access. There's nothing wrong with my internet connection either, I can access everything else fine. And it is february since i could last access the itunes store on my pc.

Basically you were not usng the right account and the site needed that to load and your browsers timeing thing limits how long a page could load. So just log on to the admisister/root account and then go to the site. If you still have problems check your conection. The /4/4/ is the last date that you were able to conect to the server.
