I was charged correctly for my purchase (in U.S. Dollars).

They are usually fairly responsive within their weekly business hours. Let us know here if this gets resolved that way we can point others to the same solution if they have the same problem.

Yeah, thanks for suggestion. I am waiting for the purchase to appear in that turnovers bracket, to see, how much was i charged in EUROS in the first place....the preorder screen said about 27 or 28, but then the receipt is again in US dollars...  now i could live with the fact if those 40 dollars would translate straight into 40 euros, i would buy the game anyway, but even then 40 + 40 is 80, not 100, so it still does not explain the whole thing. 

EDIT: Reading Thoumsins post, yeah, i will do that. Just to be clear, I am not blaming StarDock in any way, i am just fairly inexperienced with this internet banking stuff, so i wanted to ask, whether i am not missing something. And being paranoid, i am more concerned about the overall safety of my bank account, than losing 32 euros.
