Its a common Error well known by the german Elsword community.
The Hackshield is blocking the game and won't let it start,....
I'm speaking german, so i can help with any further problems that will be posted here.
I try to find a solution in the german board asap, but i can't promise i will post them today
Just check here, if i edited something
# Windows Vista / 7: Sidebar.exe
# Comodo Defense+ (set exceptions for Hackshield and Elsword)
# Antivir Guard (set exceptions for Hackshield and Elsword)
# newest Skype-versions
# Keyboards / Mouses with Special-keys (e.g. Volume-control) or Keys with Macro-function (e.g. Logitec G-line-series)
# Hackshield and/or Elsword don't have enough rights to pass through the firewall
# no free-open ports in the firewall
# some USB-UTMS-Sticks (e.g. Medion mobile alias Aldi-Talk)
# programs / Hardware that show system-functions
# Trainer and Cheatsoftware that may be used for other games
# Virus, Keylogger aso... which access Elsword
Though the Hackshield errors differ from person to person,...
It mostly depends on other software and programs running simultaneously....
Sometimes at the first start of Elsword, u will get the error, ... retry, and the second time it will start normally!
If i didn't misunderstand, Hackshield itself got no problems at all.... it's the user's fault
