I am attempting to purchase from the US and am getting the same error message with all my payment methods.
"Result Message : [TS01] Not Enrolled. Your creditcard is not enrolled in the payer authentication program of VISA/MasterCard. Please contact your creditcard issuer(or issuing bank)."
As someone else mentioned in another thread this is a problem with 3D Secure Authentication not being widely used in the US.
Please figure out an alternative way for people to buy this, Smilegate. I have never had this much trouble trying to give a company money.
