iTunes Store Sign-In (Error -9813)

[digitalpencil]

Hey, when i attempt to sign in to iTunes, or create a new account (current ver (9.0.2) i get the following error message.

We could not complete your iTunes Store request.
A unknown error occurred (-9813).

There was an error in the iTunes store, please try again later.

--------------

I can sign in via my iPod over the same wifi connection and via my brother-in-law's Powerbook, why is my MBP refusing to sign in?

I've searched high and low for the error code -9813 and can find no documentation anywhere. It has been doing this since yesterday and the error fires as soon as it attempts to connect to the server however the store content (pre-login) all loads fine i.e. adverts etc within iTunes.

Any ideas what this error means? how to fix?

Thanks,

DigiPencil

solved.

for reference, error was in corrupted keychain items. restore keychain entries, reboot, repair permissions and retry. should solve 9813 error.
