iTunes store not working

[psgamer0921]

Is anybody else having problems accessing the music store? Specifically the Gift Certificate's portion? I keep getting "We could not complete your music store request. An unknown error occured (5555)"

What's that mean?

I know it's a lot later than when you posted this, but the store is working fine for me.

Errors happen, sleep on it and try again tomorrow.
