Thanks weltall, will include this in the next version of course. For now it shouldn't be too hard to open the script in a text editor and find the following part near the start:
# hardcoded config
CONFIGDIR = '~/.PStools'
CONFIGFILE = CONFIGDIR + '/PS-PlayerS.py.ini'
XMLINFOFILE = CONFIGDIR + '/playerinfo.xml'
PLAYERTAGCOUNT = 192
REPORTTIMECOUNT = 98
REPORTTIMEOUTMSG = 'Timeout!'
RACES = ("unknown", "Ylian", "Xacha", "Dermorian", "Nolthrir", "Stonebreaker", "Hammerwielder", "Lemur", "Kran", "Diaboli", "Enkidukai", "Klyros", "Ynnwn")
Change the "PLAYERTAGCOUNT = 171" in line 37 to "PLAYERTAGCOUNT = 192" and save. The script should display the names after this change again.
