The first bug window says that you need to install the fonts.
As for the second bug window, I'll ask Zeus to have a look. I don't know why it's not working on your computer.
Just to clarify a few things:
I think it is because a few audio files are missing, you you renamed something without changing it in the editor.
There isnt a lot of information here about the story and whatnot, if you give us more information itseasier for us to critique. Your artwork isnt very good. There is somepillowshading going on. I appreciate the custom artwork, but its not super quality art. Your maps are bland and without focus. there isnt anything going on in them and they are boring an mundane. Add more stuff to them and give them more structure. I do appreciate however the nice looking ABS system and the custom features that you have implemented and I think you worked more on the technical side than the artistic side. I would go back and try to clean up a few things. This also may be your first game, so you are learning the basics.
I'm Creation, the creator of the game is Zeus. I translated his game ;).
As for the story, I will update my first post.
I also think the art isn't that bad (and Zeus has actually improved his drawing tremendously
since this demo was released).
If anything, try the demo for the technical side. I've yet to see something as advanced as this in RPG Maker XP games.
