[IMPORTANT] Please Help!!!

[KiKi_Vanilla]

I have just donated for Vast Rank and used my mum's Credit Card (Visa).
Then I logged in (on the same computer) as Dr_Milkshake my sister and entered her Username to donate.
But when i entered everything as i did before - it said:
'The Card you have used cannot be used to make this Payment, please try another credit/debit card number'

I don't understand! I did everything exactly the same!
Is there some simple explanation?

I really need help on this

The card probably ran out of money.
