Use VLTEd 2.0., I am not sure which nodes are housed in which file as the editor loads all of them at once.
Good news is that backups of all files are made when you first make any changes ever - then if you mess up, you can just rename *.bak to *.bin.
Also that probably explains why it doesn't throw the "cannot save" error that first time - I bet nfsu360 forgot to check for the *.bak already existing and it's trying to make a copy that already exists or some such silliness causing the error - as all files are modified fine and the exporting works for 300+ changed fields patches.
