Tell you ahead of time, to play JP Elsword, it's a bit annoying to work with because I think VPN works better.
You only need the VPN all the way until you hit game start. While you patch, it'll just fix the connection and you'll be able to get in the game normally.
mobilefree.jp used to work, but I don't know if it works anymore. I use to play using PacketiX. Well I hope this works for you in a way.
