I added $10 to my account and then tried to add another $5 right after so that I could have a total of $15 to buy the new COD map pack. The first transaction worked without a problem but on the second transaction a message appeared saying "The credit card information is not valid. Please check your entries carefully." I used the exact same info as before and I double checked multiple times and I get the same message. Can someone tell me whats going on? Thanks in advance!
