If anyone's using the Visible Upgrade mod ( Moddb.com - which you should be if you aren't), you'll need to edit the DX2UI.ini in "C:\ProgramData\Deus Ex 2 Visible Upgrade\Installed Mods\Unified Texture Pack\System" instead.
There's already a [DebugMenu] entry in there, so you'll search for it and paste over it with the text from the DX2UI.ini in the zip file.
