Problem with purchasing from online store

[Trooper911]

Hi

I'm trying to purchase ArmA 2 Combined Operations from the store. Everything went well till I received a confirmation of my purchase. I then had to go and view my purchase (since it didn't actually ask for me to pay for it before?...) and I selected Mastercard and then clicked pay now, but after that it comes up with an error... Any ideas as to what the problem is?

Thanks.
