I used Earth's save without a problem. Hence the updated version I posted. I am currently up to 53 cars, so will maybe post another save later. Ought to have a complete save sometime tomorrow.
The only thing that can cause corrupted data is to miss out a file or to somehow rename the game directory. My version of Earth's save can be extracted directly to a USB stick so you might like to try that to see if it is any better.
