Edit: NCSoft solved the problem for me. If you have any trouble installing the game or downloading the newest patch, contact them.
the beautiful NCSoft launcher is making me crazy. I'm trying to install this game for two days now and it's not working. I've already tried almost any common fix solution (deleting antivirus, turning off my firewall, proxy, internet properties, etc.) but even after a few reinstall attempts the outcome is still the same: The launcher downloads a 9GB patch (version 27, yesterday 26), goes up to 99% and error E02018 shows up. Launcher says only 10MB are missing but he just won't download them. My whole download folder (C/ProgramFiles/NCSoft) has arround 24GB even though I didn't download that much (how is that even possible?).
Now its stuck at 9% and everytime I start the update again my download speed (6 Mbits/s) goes from ~700 Kb/s down to 0 Kb/s. A few minutes later the error message shows up again.
I really hope that someone can help me with this since I'd like to play this game.
