New and fixed (hope) version 1.4.1
@Emmanuel
You are a good teacher! Thanks!
I've try to fix bug that make plugin to don't do what we expect in some circumstances.
Now I hope it work with unique level file (old or new) and also with demo files.
Don't ask me what I'm done because I don't know.
I'm sorry for the inconvenient!!

PS @ Emmanuel
I've read Your reply after I make this post.
I've found the same solution but after 4 hours of investigate the code by inserting spays on different stage.
Thanks a lot!!!
