RAR? Have you unrarred the game? Saves don't work if you're playing it through winrar.
Usually when you do stuff in the folders while in the game, it can bug out.
To save there should be a "save" folder in "www" folder. And inside that should be
config.rpgsave
global.rpgsave
and then file1.rpgsave and so on, if you have saves. You can make the other 2 appear if you delete the save folder and start and save a new game. Then you can just drop your previous file(number).rpgsave or the whole inside of your previous build's save folder into the new save folder.
edit: do you have a save folder inside the save folder? That's not how it's supposed to be like. There should only be the files above in the save folder.
