I have GTA IV installed on my computer and I have installed a mod called "Realism". I thought I backed up all my files but I didn't back up these : ext_veg, filecheckfix, rage_postfx, dsound.dl and all car files. I didn't like the mod so I replaced it with the original files but in the game I noticed that (example.) the car turismo was actually a Ferrari and the Sprunk ads are now Sprite ads. Does someone has GTA IV installed and can he send me these files through e-mail. (Sorry if there is any bad English, I am a foreigner) :)
