I had the same problem trying to use v5.2 for CS 1.5.
I opened up liblist with notepad from v4 of epodbot and copied the text. I used the text from version 4 because when I installed it the maps were visible.
I then installed 5.2 and replaced the text in liblist.
ie
Open up liblist with notepad and replace the text with:
game "Counter-Strike"
url_info "
www.counter-strike.net"
url_dl ""
version "1.6"
size "184000000"
svonly "0"
secure "1"
type "multiplayer_only"
cldll "1"
hlversion "1111"
nomodels "1"
nohimodel "1"
mpentity "info_player_start"
gamedll "EPODbot\EPB.dll"
gamedll_linux "dlls/cs_i386.so"
trainmap "tr_1"
