Yeah i have v5 and the radio menu comes up as #RadioA, #RadioB and #RadioC for z,x and c also when u win around cs displays *CT_win its all weird and stuff...
well this _is_ caused by EPB as you packed the CS 1.6 titles.txt into the package. So before installing EPB, please backup the original CS 1.5 titles.txt and after installing copy it back and then append all EPB contents to the titles.txt.
