[Guide: Errors, installing, game-crash, delay]

Well my damn game keeps crashing over and over again... I keep getting a crash report during the NCsoft loading screen. The game worked before when I restarted my comp, but now it doesnt launch at all... It says:

An error has occurred in your Blade and Soul client. An error report has been made regarding the status of the installed Blade and Soul client, your hardware configuration, the DDl list loaded to the memory and data relevant to other client errors.

Another thing is, my FPS is at 15 on a 5 and 20 on a 4 (graphics settings) constantly and the game laggs. When I played on the Chinese server a year ago and on the Russian server this summer, my FPS was at stable 40-50 on full graphics... Did they change the graphics or is it just because of Alpha? My GPU is Nvidia GTX 860M 4GB Kepler, so the game shouldn't be a problem for my GPU at all.

Really frustrated right now because this has been going on since alpha... Kind of want to play the game but support system here is useless.
