I've only recently aquired a PS3 and started GT5, I was so happy to see this thread after finding out that the online functions like DLC don't work anymore.
Your tutorial is nearly perfect and everything worked.
I have only two very minor suggestions.
I tried starting the editor from a network drive, which didn't work (can't find database), copying it to my local drive solved this issue. It's not the first time that a software doesn't work on the network drive, so finding the solution was obvious to me, but you might include a hint on this.
In the tutorial the "I suggest a backup before loading the save in the editor" comes right after the "load the save in the editor" step, I suggest putting that before that. Again, this didn't cause me any trouble (I tend to fully read a guide before doing it step by step), but other people might.
Thanks very much to the developer for the editor, and to you for the tutorial.
