go to where you gta folder is, USUALLY it's in your hard drive folder (under the computer option in your start menu, listed as C: ) program files (x86) ((if you do not have this folder, try program files)) rockstar games, Grand theft auto IV OR EFLC and look through the files there to look for those, A reinstall would correct the no lcpdfr issue but running the installer as admin, Right click and run as administrator. an idea occurs that you delete the xlive's and dsound's from the gta folders, and reinstall lcpdfr and do not check xliveless when you install it
