Hello,

So MoM is on sales, and I decided to buy it.
However just after putting my credit card info, I get this "Your credit card number was invalid."
The thing is that I bought a game a week ago with that exact credit card.
I deleted cookies etc, still nothing to do about it.
Any idea? Maybe it has something to do with Heartbleed thing?

You should contact your card's support but are you sure your card is not expired or over its limit?

If the message is appearing immediately after clicking the confirm order button, then just double check the card number as the chances are, you've entered the number incorrectly.

If the message appears after a short processing message, then it's likely to be your card that's the problem. Some card issuers have random checks against transactions for fraudulent activity, so they may just have prevented it clearing and should have contacted you.....

I verified the number hundred of times.
Just bought something from another website and it worked great.
So it must gog related.

Nobody should have to live without Master of Magic. Check your PMs.

Thanks man you are great!!
