Okay I am having this error come up with only some modded cars. I thought this was just due to bad mods, but I ran into something interesting today.
I downloaded a Mercedes CLK GTR + CLK GTR SUPERSPORT mod a few weeks ago. Both versions of the car would crash when the car began loading. Today just for the hell of it I decided to try to get the regular CLK GTR to work again, so in content manager I used the "pack .data" function to convert the data folder that the mod came with to a data.acd file. I tried to run the car, and it finally loaded!
Great, I figured it out I thought, so I did the same thing to the CLK GTR SS version, only to have it crash in the same manner as before with the Race Cancelled message.
I have gone through every single file and folder, including all in the data folder and compared the one that works to the one that doesn't.
I also made sure the driver model was pointed to the right file name.
As far as I can tell these are the exact same car, but the SS has different skins, and some different parameters in the data folder that make it faster than the base one, but all of the text is correctly formatted and placed. I can also take all of the skin files and put it on the CLK GTR that works, and the car will still run with those skins.
The error logs are a little cryptic for me to decipher, honestly I am not even sure which file to look in for that as it seems there are a couple .log files it could be.
A side note, I was also having the same error with a McLaren F1 mod, and a BMW Z3M mod.
The McLaren ran after converting the data folder, but the BMW still crashes.
Any help understanding where to look in the error logs, or any other enlightening details towards this issue are very appreciated.
Thanks
