I'm trying to buy Humans must pay.

When I get to the checkout page I enter the credit card numbres and exp date, click the green button and nothing happens.

Anyone else having trouble paying for something today??

This is the first time this happens to me

Do you have a script blocker active in your browser? If so, check to make sure it's not the culprit.

If you haven't already I would highly recommend you contact GOG support directly.

First off, check the account that you paid with if possible and see if a purchase has been registered.
Second, if payment hasn't been made, use a different browser or give it a short while of time before trying again. Sometimes the site gets busy and doesn't respond well to certain browsers.
Third: If neither of these resolve the issue or if payment is registered with the account in question, send a support ticket to the staff to get your game.

I waited for an hour to see if the problem solved itself but it's the same, but I was abel to pay using my paypal account.

I think it's a problem with the VISA module or something like that.

I've contacted support nevertheless so they are aware of the issue.

Thanks

I've just gotten the support reply.

Turns out it's a problem with font scaling. It waas set to a 120% on my browser and that caused the cardholder's name field to dissapear. Without the name, the system doesn't process the order, hence the green button not working.

Everything is allright in the world now.
