I send a mail to Logress, but since I have not received any acknowledgement I put it also here:
I tried both Paypal and Credit Card (two different cards), and always refuses to do the payment. I can provide screenshots, but basically the messages are:
Paypal: Paypal has rejected your payment attempt. Please select another way to pay. We apologize for the inconvenience.
Credit card: We're sorry, but your credit card was declined. If you feel this is an error please contact us.
On my paypal log, the payments appear as: The seller cancelled this payment and the money has been returned to your account.
I would like to have it solved before the current 3-star sale finishes
