Can you try this?

Close your iTunes,

Go to command Prompt -

(Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".

(Win XP SP2 & above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt

In the "Command Prompt" screen, type in

netsh winsock reset

Hit "ENTER" key

Restart your computer.

If you do get a prompt after restart windows to remap LSP, just click NO.

Now launch your iTunes and see if it is working now

I have performed all of the tasks above and my itunes still does not respond after signing into my apple id and then doing something with the iTunes Store. (ie. Try to update Apps, go to iTunes Store, iTunes Match, View my account.)

My account works on my devices and my 2 other authorized computers.
