I dont think I did it incorrectly. I just went into the Data.zip file and changed the numbers in the project_config folder. Then it didnt want to save it in that folder so I saved that particular file to my desktop. After that, I found the file in my desktop and simply tranfered it to the file in project_config folder and deleted the existing one. Let me know if I did it incorrectly.
upload your stock data.zip and we will look at it and make the changes for you and reupload it and it should work for you then and we can then say that data.zip is for the 500 models if they are infact different but i need to see one first
