Alas, I’m afraid that we’re unable to replicate this one over here on our end (i.e. license renewal orders are working just fine for us here). Do you happen to have any ad/popup blockers enabled within your web browser? If so, then you may want to try temporarily disabling them just to see if that resolves the issue for you. If not, then you may also want to try using a completely different web browser (or perhaps even a completely different PC/device) when placing your order.

Other than that, if you’d like to contact us via our email support page with the User Name from your existing license, then we can try providing you with a direct PayPal link for submitting your license renewal payment. Although, I’m not sure that will make much of a difference seeing as you’ll still be going through the main PayPal user interface (and that seems to be where you’re having the issue).
