I have a problem buying points

I tried to buy points to have a conversation with my tutor. But I can not buy points on ‘point page’. When I click ‘buy points’ button the following massage shows up. It says ‘‘PayPal Server Error: The Reference ID refers to a transaction or order that is more than 365 days old. 11457. Referenced transaction or order is too old’’. I have not had any problem buying points before. How can I solve this problem? Thank you.

@chikaraishihara - Sorry for the trouble! Would you try clicking the Edit link on the page to update your payment info? It looks like it’s still using your PayPal account to pay for some reason. Once you update your information on that page it should work properly.
