Throw *DevaStation(q2_q3dm11).pk3* into your baseq2 and fire up kmquake2 or kmquake2_x64, then open the console 

and type *disconnect*, then *deathmatch 1* (because kmquake2 is set to single player as default, and we want this map

in deathmatch mode), after that type *map q2_q3dm11*

there you go .... :)
