I have that problem...I seen the last thread but it was a bit confusing and it was closed. When I try to run Maple Story, that comes up. What do I do? Im not good with computer things. :/ So if someone could tell me step by step on what to do, it would be great. :]

Begin by reading the following section of This Guide.

I just quote the preliminaries. Scroll down the page for information of detecting your hardware and locating the proper drivers.

[3.0.0] MapleStory

[3.1.0] MapleStory Errors

[3.1.1] "Failed in finding proper screen mode for Gr2D"
This section would be helpful to you if:

--> you have reinstalled Windows recently on your computer;
--> you have never played MS on your computer before;
--> you are trying to run MS in a virtual machine (jump to [3.1.1.6] now);

This section does not apply to you if:

--> MS worked on your computer before but you have not reinstalled Windows between now and the previous time it worked;
--> MS worked on your computer before but due to a patch or a GameGuard update, it no longer works;

If the last two applies to you, I suggest you do some universal fixes right now: reboot, reinstall the client, redownload and reinstall the client, system restore to an earlier point where it does work, and/or email Wizet (but make sure you mention that MS worked previous to a patch or whatever event that made it not work). It also wouldn't hurt to try these sections, but you will have a lesser chance of getting it to work compared to the people these sections are written for.

Its still a bit confusing...D: I dont really get a thing...

Did Maple Story ever work on this computer?

If not it is probably not capable of running the software.

If it did run before you probably need to update your graphics card drivers.

No, it has never been on this computer before...Its a pretty old computer.

That error indicates that your graphics hardware is not sufficient to run the game.

You need to upgrade the computer or at least the graphics card.

How do I do that?

What is the make and model of your computer?

I'm...not sure if that sounds right...It says Gateway on it. Sorry, Like I said, Im not good with computers. D:

See what this scan says under System Model as well as Display:
