Yes, I too have this horrible problem.
Yes, I did read some of the other posts.
I have an ATI RADEON x850 series graphics card, and already updated the driver.
This is an old computer, first time trying to run maplestory on it.
I have DirectX 9.0 on it. But whatever, here's the information from dxdiag.
