Hi my mastercard has enough money on it and I´ve tried 4 times to delete card and put data in again, so there are no writing faults or sth like that! The only difference between my adress in sl and my billigadress of the card is the "ß" in Straße (wich means street in Germany) but I cannot insert ß in the sl payment data only "ss" ... don´t know if that´s the problem?? Otherwise I don´t know what else to do. Without LInden this game doesn´t make sense to me and I´m near to give up :(( my card works very well on other platforms like tribalwars.us ... so I don´t know what´s the problem! Greets, Jana
