                    Hi,
I recently got a new laptop and I was to purchase a license. On my old laptop, I only had the free trial. Now, I'm at check out but the error:
:Your order has not been completed
Error code:G12
Credit card is unusable."
I used every credit card I have, but the error still stays.
