As most of you have probably noticed, the most recent GTA4 PC patch caused compatibility issues with most (if not all) previously released ASI modifications. Although there may not be fixes for the specific scripts there is some good news, Alexander Blade has updated his Alice script engine, which allows you to install LUA mods for GTA IV.
You can grab a copy of the updated script from here, but note that mods will no longer work in multiplayer in line with rockstar's banniong of mods online.
