Hello,
Are you and your husband playing on different computers ?
Do you know how to copy and paste a file, a folder etc. ?
If yes, all you have to do, is copy the Allods game client from your husband's computer (on a usb drive or through network if your computers are on the same network), and paste them on your personnal computer, replacing your Allods game client.
Allods Game client can be found here : C:\MyGames\Allods Online
Another test : try to log in with your husband's account on your computer. Does it work ?
