i have forgotten my login info for multi player! is there anyway to retrieve that info?

Probably not, since Kalypso is a small brand company and the only way they can make money is to NOT put a retrieve game info in the game, but to add insult to injury to ask for your email in the registration like they actually give a damn about u the paying customer no matter how long u supported them, ur only good to them as a paycheck probably why big name company's beat them out every day of the week, i bet if i forgot my xfire or steam account or password there would be reasonable way to find them, but with Grand Ages Rome its remember or fuck off. i hate this bullshit corporation.

You can use the "change password" option from the login window to reset your password. If you can't remember your user name either, please contact support@kalypsomedia.com, providing your game's serial number.
