[jaroslaw]

Hi, i installed gta 4 today, updated patch 1.04 in gta, used the magic thing to make my game moddable. Used sparkiv and followed a youtube video to add cars. Now when i start game and play, about 7 cars i replaced are missing, i was driving around for about 30 min and there is no sight of any of the cars, new and old that i replaced?? Plz help??

have you tried un-installing the game and then re-installing and then wait like a day to install the mods on to the game? Try that and see if it works and if it don't then just seek expert advice from rockstar! :]
