We try our best to make everything go as smoothly as possible. Unfortunately there is always a possibility that something goes awry. If you receive an error message when you want to finish your payment, please take a screenshot of the error and contact us. We will look into it and fix it as soon as possible.
A possible solution you can try yourself: Log out, download another browser (good examples are Chrome, Firefox and Safari), open a window of the newly installed browser, then log back in to btcdirect.eu and restart the purchase order!
