I'm getting kicked out to Windows when I try to play MapleStory.

You may be kicked out to Windows for the following reasons:

1. Illegal programs are in use on your computer.
2. A downloaded patch file is damaged.
3. The current Maplestory Install is damaged.
4. The MapleStory client was changed.
5. There is not enough memory or there is an issue with your Direct X version and graphics card driver.
6. Windows system files are damaged.
7. Region blocked. Click here for more information.

To remedy the problem, try running a virus scan and then uninstalling and reinstalling MapleStory. You may have to reinstall Windows if there's a problem with your operating system.
