So yesterday i wanted to add Lamborghini Aventador Add-On to my modded game copy, but i ran into issues. The game would start crashing as soon as i install the mod. I followed the instructions provided by the mod author in the readme, but no matter what i did. As soon as i place the mod files in their respective place the game just crashes while loading story mode. I just get GTAV.exe has stopped responding error and it closes. I tried removing the mod and placing a different one, same issue, game immideately starts crashing while loading story mode. I went ahead with removing the mods (add-on) cars and it works. Confusing thing though, few days back i added another add-on car and it worked. Now none of them work, the game is just crashing.

 

If needed i will provide the links to the two mods that i tried using.

 

Any help would be highly appreciated!

Found the issue, editing gameconfig.xml file causes the game to crash. Have no idea how to get around this. Still need help.

I am having same issue. Only mine doesnt even get to loading story mode, it wont even open if I try to add any vehicles. Just crashes immediately. I have followed all instructions for all mods and have used OpenIV to add mods, and it never works. I have tried every single vehicle mod available on LSPDFR.com and none of them work. 

It basically has to do with the gameconfig.xml file. When the game gets naturally updated, the xml file updates to accomindate the new dlc packs, however when you add a dlc pack of your own and the xml file isn't updated, then the game will crash. 

i don't get them to work at all, i'll add them in, for example, the hellcat charger, add it in using the OpenIV, can click on the buffalo file and view the hellcat, load the game, nothing. Or i can even close OpenIV, reopen, and go back to look, it's back to regular buffalo
