We're very sorry it's telling you your Apple ID is incorrect. It's a bug with iTunes. It seems to affect about 1% of our users. Most people have reported that it was just a temporary problem and it worked fine later.

However, we have set up an alternate payment system though PayPal if you'd rather subscribe that way.
