itunes edit payment final click button disabled

Sorry if this is a duplicate, please close it then.

Before you ask: I'm from germany using a german itunes on a macbook pro 15", snow leopard, latest updates (yesterday).

I've been trying to change my payment method from credit card to click and buy.

Every time after I've run through the activation procedure, i.e

• being forwarded to the click and buy page
• logging in
• enabling permission for itunes
• being redirected into itunes
• itunes displaying "Sie haben Ihr Click And Buy Konto mit Erfolg validiert" (translates to: "You have successfully validated your click and buy account")

the final "OK" (in german it display the label "Fertig") button looked disabled.

So I thought I'd be OK, and everytime I tried to buy somethiong it showed me that I'd not entered a valid payment method.

BUT: The above mentioned button only _looks_ disabled, it's not!

So when I clicked it, it stored my account data.

Just letting you know that this has been _very annoying_, keeping me frustrated, and thinking about using something else to buy my music.

Sorry to bother anyway.

So if anyone is experiencing the same thing, first try to press the buttons anyway, ignore when it's displayed like it is disabled ;-)
