Did you read carefully the part about replacing the original La Rochelle building.dp files? I had to correct a couple of the .dp files in order to get the scenery to work. I fixed the .dp files and re-uploaded the La Rochelle package on June 15th, 2013. If you did not update those files, CFS2 is locking up because those .dp files are flawed and are not generating the .cdp files.
You need to overwrite the original .dp files for the La Rochelle scenery with the updated ones in the package, and make sure to delete your filelist.dat and .cdp files, allowing them to regenerate. That should fix your issues, my friend.
