SHUT UP AND TAKE MY MONEY PLEEEEEEEASEEE

ive bought plenty of rp before on my desktop computer, but now that im on my macbook it crashes the entire game when i go to select what type of credit card i would like to use. Ive tried entering it in backwards and making the card selection the last step of the process, it still crashes as soon as i select my card type. I just want to give you money, so please help me.
