Tenseiga

When I press the Blade and Soul icon on my desktop it redirects me to the NC Launcher. Then when I get there it says I have to update. I press update but then it says. Cannot find the file. Click the Update button again. If the same error persists, it may be due to ISP authentication failure, NAC, or a virus. DD_D:\Program Files (x86)\NCSOFT\BNS\bin64\TPS_UE3.pdf (2) and I have no idea how to fix this. I have the new version of the NC launcher installed. It says I have BnS installed because the icon is on my desktop. I don't know what else to do.
