Hi guys i have a question. i play on the EU servers and Cataclysm is realesed, but unfortunatly my retailer is going to get the hardcopy in a month, so i went to battle net and to the digital downloads but i didnt find cataclysm so i google searched cataclysm digital download and opend a battle.net site for the PRE ORDER cataclysm digital download so my question is, if i buy the pre ordered version of the digital download, will it work? thx for your time.
