Paypal not working!

I tried to become a subscriber, but paypal won’t allow me to! From the Ardour site I am redirected to Paypal, login, and then nothing happens!!! I have Mac OSX 10.6.
Thank you

I think the problem is with Paypal, US/UK miscommunication, nothing to do with your site… Sorry, I will try again in the future.

Sorry, I have no idea what the problem is. People use PayPal almost every day to become a subscriber (2 in the last 24 hours).

SOLVED: If this can be of any help: Paypal doesn’t like Adblock Plus in Firefox, at least in my Mac. Once I disabled Adblock I could do the subscription.
