i changed my mods folder and renamed it to _mods which allows me to boot up rage and use all the systems and menues i habe such as script V and the f4 ELS works as i see from pressing scoll lock but i cannot use any of my replaced or addon vehicles pleases advise

If your game is just straight crashing, undo any recent installations or changes you have made to your mods folder. There is a chance something became corrupted when you installed it. I cannot accurately tell you what it is as it is near impossible.

thanks for the reply I have deleted the mod folder completely and slowly re installing the cars and loading up the game after every install , no issues yet might take a while but rather be careful
