For first time installer
-Download BnS_Lite_Installer from bladeandsoul.com
-Download the torrent file from this link https://www.reddit.com/r/bladeandsoul/comments/41pbsf/for_those_with_unstable_download_speeds/
-Install BnS_Lite_Installer
-Run Blade&Soul Client
-Update
-Close the launcher
-Copy "Patch" torrent file into directory inside $Patch$
-Run the launcher again, let it finish checking everything and then start to run 2nd stage of downloads
(For those stuck on second stage)
-Copy "Patch" torrent file into directory inside $Patch$ ( Yes, again!)
-Run the launcher, now the launcher will finish 2nd stage and now you can play past Viridian Coast.
As for version 11, it will have no problem. After you finish installing second stage, it will auto download additional update (if there is any).
Hopefully this helps
