My mistake. I removed the handling from handling.cfg, and added it using the handlingadder.ini, but it still crashes. Exact same error message.
It says "last file loaded: DATA\VEHICLES.IDE", so i thought maybe it's something to do with that. But there's nothing wrong.
I removed the # in the limits thing, and the game launches. The cars display but they are in the ground, like this:
And when enter is pressed around them, the game crashes with this message:
NINJA EDIT #2:
ISSUE FIXED! It was a problem in vehicles.ide.
Instead of 612, stratus, stratus, car, STRATUS, STRATUS, null, richfamily, 7, 0, 0, -1, 0.7, 0.7, 1
I put this: 612, stratus, stratus, car, STRATUM, STRATUS, null, richfamily, 7, 0, 0, -1, 0.7, 0.7, 1
As you can see i changed that one line from STRATUS to STRATUM, and it works.
However, now i have a different problem. The car has no sound.
