If you still have the log file for this I can investigate. There will be an engine_crane.log file that is created in the same location as the engine-crane executable that you run.I can't add the engine to the car, I receive an error "missing data section engine [a lot of numbers]" help please
You can raise an issue for me to look at here: https://github.com/zephyrj/engine-crane/issues
Explain the what you were doing (import from BeamNG mod or engine-crane custom export), what car in AC you were trying to swap into and please attach the log file when you raise it. With this info I can look into the problem
