I am not being able to sell even one of my cards now for some reason. I know from a long time back that you are allowed to AT LEAST sell one card per day but now it's been like two weeks since i've sold any card and this message keeps on appearing:
To prevent cheating, the public and private sales (excluding sales to Kate) functions will be unlocked indefinitely after your first purchase of credits at the Shop (more information can be found in the Game Help section).
Can somebody please help me to sell my cards once again.
You need to buy credits or do one of the free credit offeres (some unlock the market and some don't but theres no way of telling which sorry).
They only did the 1 a week for a short period of time and then changed it back to no sales.
