I just installed this game, updated everything etc.

When I launch knight online, I get a screen where it says 'start / homepage / options'.

I click on start, something small will appear at bottm right, with .trap orso, after it's done the game won't load.

Any help?

X-trap really sucks, if it finds a virus or hack of any kind on your computer it will not let knight online play, (It wont tell you where the virus is either )
Back when I played all you had to do to get rid of the x-trap message was to run the game on a limited account, by that I mean an account on your computer that is NOT an Administrator, then X-trap wont run.

Hopefully that helps
