I've trying to check out on Marketplace, but when I click "check out" this message shows up and I don't proceed to the payment: "We are unable to process your order at this time. Your items will remain in your cart and you will be able to try again later." I tried closing down my browser, restarting, but the problem continues. I have more than enough L$ to pay for the purchase but in any case it won't get me to that stage. There aren't any issues with duplicate items, or anything like that. Any suggestions would be useful.
