Genesis ENews Extended Plugin -Can't install AWeber

I tried today to add AWeber to the widget and I used the tutorial from Brandon but I got to an AWeber page:

https://www.aweber.com./scripts/addleads.pl -saying “Oh NO! The page you are looking for does not exist.” Any ideas what I did wrong?

My site is: https://www.harmonicpod.com

I tested MailChimp on Saturday and got that working but I’d like to use AWeber instead.

Thanks for any ideas that you have,
Lee
