If you would still like SparkIV... Because everyone pretty much uses this as Open IV is time consuming. Place the SparkIV files in your GTA IV Main Folder... it wont affect your game. Then if you have an asi loader (dsound.dll) remove it and download and install xliveless-0.999b7 to replace asi loader then run as admin and you should be set to go!. Please let me know if you have any questions... Hope this helps..
