M41l0.scr is the script file for M4l0.map. Launch mohradiant then open M4l0.map. The script file is a text file and can be opened with a text editor. Right click on the file in explorer and select 'Open with / Choose Program ...' and choose a text editor.
I have associated files with the extension .scr with my favorite text editor by checking the box "always use the selected program to open this kind of file" in the window that pops up when you do the above.
and if that wasnt simple enough look for an icon that says MOHAA radiant (i beleive thats what it says) and click it twice with the left button on your mouse as fast as you can... the pic of the icon should be a badge with alot of red and stuff... (apparently not looking at the icon at this moment)
