You need to Extract the .BZ2 compressed "Fast Download" File with "Winrar" or "7-Zip" software to decompress/get the map.bsp
Place the map file called "dm_ob_nightmare_church_rc2.bsp" when decompressed in the maps folder, load up HL2DM and select the map.
E.G. C:\Program Files\Steam\steamapps\Your-Steam-Name-Here\half-life 2 deathmatch\hl2mp\maps
