I extracted player9.dff, changed it name to player.dff and replaced original player.dff with it. I did the same with .txd at first, for a mistake. When game stoped working i dragged and pasted original gta3.img into models folder, replacing the other file. I think that's when i made mistake. I used to delete gta3.img first and then copy and paste original file. I have win7 and i think that this might be the reason too (i had some problems with vc already). And i also could possibly click join the files what coused fucking up both files - this makes the most sense to me.
