I'm on Windows 10 with latest IE.

Hi, it's not mandatory to use a credit/debit card. PayPal is awesome as an alternative. If you're having issues with the page spitting you back out, or bringing you into a loop, I would recommend using another browser, or device. For you, I would try using Chrome and signing up. If that doesn't work, try another PC. More often than not, I've found that a browser or the way the internet is set up on a computer can mess up purchase fields like this.

I hope that helps.
