@Grider72 oh ok, well the problem with that one is that you need to put .yft and _hi.yft files in one place and the .ytd , +hi.ytd in other place... so, i don´t know witch version is your game but try this:

1.Open "OpenIV"
2.Press"CTRL+F3"
3.Write "stalion.ydt"
4.Wait for results, look for the folder were there is only 2 .ytd files (stalion_hi.ytd and stalion.ytd) make double click on one of them and this will take you to that location.
5.Replace .ytd and close.

Hi, looks like the game is not reading .ydt file it´s just reading .yft... which car are you modding?
