On the config you are trying to use inside of the Ashita launcher, right-click and choose to Edit it. Then click 'Advanced' on the left and edit the PlayOnline language to the one of what you have installed. By default it will try to use the English client, you probably have the European client which you can set it to either Euro language. (This is just the language of the registry to find where POL is installed, the client will still be in English.)
