invisible terrain

what's wrong with this terrain?
i've patched via NCsoft, on my laptop (vista dx10) and my PC(xp dx9c), both come like this

not only here, but at inggison fortress, oriel (housing map) too..

 

Fixed, was a problem with the anti-aliasing.You need to enter the graphic options and now 3d - anti-aliasing- select ''use application settings''.

 

this right?

i've only had option : enhance or override application setting..
i've tried enhance, and no differences yet

 

My graphic is not the same ... Before it was better ... and i see one thing make me sad, the mount Waveform Surfrider lvl 60 is in shop for 2500 toll, normally npc sell it too ... but we cant buy it to npc, we MUST to pay to have it ... its shameful ...

 

the npc one named "Airskim Surfrider" if i'm not wrong.. and it's fabled class(req>=lv50) while the credit one is eternal class(req>=lv60)

btw.. i've just tried to adjust the graphic engine settings higher and the terrain appear LOL..

solved then.. =)
