Guild Wars 2

I have been having this problem off and on, and it seems to be getting worse.
I click to buy gems, then click credit card and the amount of gems I want, and sometimes it won’t let me press the next button.

Today, I was able to press the next button, but the fields to fill in my card information disappear when I mouse over them, making the process impossible to complete. I want to give you my money!

I was able to make it work by changing my payment method to paysafecard and then back to credit card. That was annoying, but I got it working.

9 days back and still broke today, lets see how far back this bug goes on the forums!

edit: okay so do what Sikketh said, i switched from credit card to paypal and back to credit card entered info proceeded and it eventually worked. Seems like bad coding to me. Someone should check the coding text to make sure all the characters are in there proper place.
