i cant buy ZP!

Well, it depends on the payment method.

Seeing how it tells you 'failed to pass security validations", I asume you are using a credit card, prepaid credit card, or a gift card. You need to make sure that there is NO spelling mistakes within your personal information it asks for. For example, your name on the credit card is 'Chase Williams' and you typed im 'Chase William' (no 'S') then it won't go through, you have to be exact on your spelling and numbers.

If you are typing it correctly thinking so, you might want to ask the person whos card you are using - If you are using yours, then you must be typing something wrong.

It will let me purchase the 20,000 ZP package but not the 50,0000 or 10,000...
