To play this map or run it on a server using Zoid's Quake2 Threewave CTF 
based on the original Threewave CTF downloading a copy of qbsp3 and do the following:

backup q2e1m4.map
rename ctfq2e1m4.map to q2e1m4.map
run qbsp3 with the command line:
qbsp3 -onlyents c:\quake2\baseq2\maps\q2e1m4.map

It will take a very short time to process the map whereby you can then use it for CTF

If you wish to play the original map you can either re-extract it or run the onlyents option
with the original map file
