dlwmed.exe and win2000

[H-Hour]

I'm having some problems getting the map editor to load. I've tried the default editor that comes with it, the two editors that can be downloaded from this site, and one editor from another site and all of them load up with this error:

Dlwmed.exe has caused errors and will be closed by windows.
You will need to restart the program

I'm using win2000, as you probably guessed from the title. I've tried using that /showall thing from a different thread, I've tried re-installing, and nothing seems to work. Has anyone encountered this problem? Is it a conflict with win2000? Does anyone have any suggestions?

Thanks.
