hello,
first of all, thanks to all who have been working on this great mod, i enjoy it a lot!
however, i have the same problem as the others, as soon as i start lcpd:fr i cannot use taxis as a passenger any more, even if i close lcpd:fr and save the game and restart GTA IV.
it appears that something is changed in the savegame, because even after uninstalling lcpd:fr i cannot use taxis in any savegame anymore in which i had started lcpd:fr.
i can only use taxis in a savegame in which i did not start lcpd:fr. i use a fresh GTA IV installation without any other mods besides traffic loader and some changes to the handling, vehicle, carcol, cargrp and weaponinfo files and some new cop cars. all the necessary asi, script and net files are there and the installation of lcpd:fr displays no errors.
if i can help in any way by testing out something or supplying my savegames i'll be glad to do so.
cheers
