Well...i went to steam forums and this is what DOUGV said:
"Because we had to wait until we released DoD:S before we processed our pre-orders we submitted *a LOT* of orders all at once. Because of this, we basically let everyone who ordered play until their credit card was charged. If you card failed for any reason, we shut the game off (rather than not let youplay until your card was approved.
As expected, a percentage of the credit card transactions were rejected either on the banks end (bad address information, missing or wrong CVV2, etc.) or on our end.
Please be patient. Unfortunately we have to handle each customer on a case-by-case basis the speed of which is dictated by the accuracy and amount of information is included with each ticket. The fix for this problem on our end is currently 100% manual. The entire Support Staff is working on this. "
BAH !!!
