Payment with Daopay

So i tried today the payment for DaoPay, but it didnt worked. When i enter my email and then log in into the Ultimate Pay account, it will give me an script error and then tells me:

Thank you, you can now advance your payment in a new window.
When your payment is done you will be notified to your email.

I also waited for a half hour or more but still nothing happend.
