I uploaded funds to my sprypay account via moneybookers and then i tried to pay directly via sprypay and i got the denial message i posted above.
It is prospective as sprypay is not supported at the moment. I just thought it was because i saw the "Pay via SpryPay" button at the deposit link.
It's ok now, i managed to deposit money via paypal.
Thank you very much for your help sir !
Have a nice day and Merry Christmas to everyone
