I'd suggest contacting the ppl who wrote the script. Surely there is some info on contacting them or their website in the script or its readme.txt or help file. If you mean the old Peace&Protection script, seems to me one of the ppl who said they took it over posted here a good while back about it, so use our search feature, set it to "all forums" and expand the date range to "all posts" and use either pnp or peace & proctection as your search term. I do remember some ppl saying it wasnt compatible at the time with later versions of mIRC.
