I fiqured it out, delete the legacy version, completly uninstall it, re download lcpdfr 1.1 automatic installer, then use the installer but when you go to install it keep it on xlive for the asi loader, and when it selects the folder, remove lcpdfr from the automatic selectoin thing, so the installation folder should end with your root GTA IV Folder, then install lcpdfr, and its done.
It would seem the issue is with the legacy version of the mod
