It's OK, address should be fonline2238.net.Try http://fonline2238.net/files/FOnline2238_Client.zipThis file should be always up to date.But I recommend you to keep the client you downloaded.So only unzip in other folder and replace files that updater wants in the client you downloaded.
one more thing actually, i noticed theres no music. since i had to drag the critters and the other file, am i supposed to do something similar with the music one?
