Punkbuster...
run pbsetup file from here always works good for me to up date pb
http://www.thepopeuk.co.uk/rsqt/downloads/QUAKE3/punkbuster/install_working%20quake_pb.zip
now try that:
u have first TO DELETE all the pb files and the pb folder from your q3 install folder!
the second step is: unpack these files from me ( virus checked - VIRUS FREE ) to your q3 install folder
next step: double click on "pbsvc" and do everything what the program requires.
next step: double click on "pbsetup" -> and u will seen that your q3 game is already registered to pb.
U MUST DO!! as a update protection for these files! all the files from
me must be "write protected" --> so it's impossible for a update to
overwrite those files, and u will have always your good old working PB
files. I guess it's not necessary to describe how to do that!!
I also tested if PB are working when PB is ON (on the server).
YES, it's work!
THIS IS NOT A HACK!! ALL OF THESE FILES ARE ORIGINAL PB FILES!!
from here can u have my PB Files: http://www.mediafire.com/?h61kec5r32754i3
GOOD LUCK
Done that a "few" times.
