Message 5555

iTunes 10, Windows 7 X64

Tried to purchase an app and got the following message:

"*We could not complete your iTunes Store request. The iTunes Store is temporarily unavailable. (5555)*

There was an error in the iTunes Store. Please try again later."

Tried downloading directly from my iPhone as well and got a "Cannot connect to iTunes Store" message.

I had a buddy of mine try downloading something on his iTunes and it worked no problem.

I tried de-authorizing my computer but I got the same 5555 message.

I tried logging into my account and got the same 5555 message.

Any ideas?
