I got this error every time I tried to use the Map Editor on my laptop so I went looking for a solution. I found the one below, used it, and it fixed the problem.
That is because of your display. Here's how to fix it.dfVmedD has encountered a problem and needs to close.
1. Click Start, and then click Control Panel.
2. Click Appearance and Themes.
3. Click Display.
4. On the Settings tab, click Advanced.
5. On the Troubleshoot tab, move the Hardware acceleration slider control to the third position (from the left), and then click OK.
Note The following message is the description for this position:
Disable all DirectDraw and Direct3D accelerations, as well as all cursor and advanced drawing accelerations. Use this setting to correct severe problems with DirectX accelerated applications.
6. Click OK to close the Display Properties dialog box.
