Silk charge click and buy error

[neeyebad]

ok, i have charged some silk with click and buy, about 500 so the max silk amount isnt the problem, when i want to charge silk with click and buy again, it says : This is not availible for the Netherlands, but i charged silk before :S, i just want to ask, anyone got some solutions for this? cuz to be honest, i'm outta gold tickets

thanks already
