Unfortunately no I don't but back up your good GTA IV folder saves before I install any graphic mods or mods that I think will break that good folder.
You still can play the storyline but remember you will have a ton of mods installed. Remember to start LCPD:FR by pressing ALT+P. For a full list of keys, press SHIFT+TAB in-game.
I believe so. When you run the installer: It will ask you if you want dsound or xliveless.
Please, if you have any more Q's Just reply or send me a PM! :)
