Just tried it again today and unfortunately the problem is still there. I don't think that it has anything to do with the code as I already used it successfully a few days ago. And I did use PayPal and everything works fine until the final step where you have already logged into PayPal, are supposed to check the information and click on pay now. That's when the error occurs. I sent an e-mail to Kobo yesterday but I don't think they are even going to read it until Monday. And to top it all off, the books I wanted to buy have become more expensive overnight!
