Hi gisele,
Gpotato has nothing to do with Allods now. We're managed by mail.ru now. The homepage of the game is now
allods.com. You can find a download button in the upper left corner of the page. To make it easier, this is the download page:
http://en.allods.com/download.
I suggest you first uninstall the old version(s) of the game, and after that start the new installer you just downloaded.
We now have two Launchers for the game: the old one and the My.com launcher. When you'll start the installer for the first time, you'll get the My.com launcher. You can learn how to use it here:
http://en.allods.com/mycomgames.
After you start the download of the game, you can start playing after about 1.3GB downloaded, but I recommend waiting for the whole game to be downloaded.
One other important thing to know is that if you'll use the old Launcher, you'll have to log-in using your email adress, not your username. But chances are you won't have to use the old Launcher, since the My.com Launcher is pretty good
I hope this helps you. If you have additional questions, feel free to post here.
