I sorry, but i cant do anything bout megaupload, if any one gives me another hosting site then i can probably hosts it there, but so long it seems that you will have to ask someone to send it to you or install the tool bar... sorry

And the thing bout that the demo does not start, i don't really know why, try to rebuild the level, and if that does not work.. then i don't know. i have older version that 7.07.. and i don't really have 3dgs left installed on my computer any more, so cant go in to some trouble shooting.. sorry
Maybe someone else can help you with that, or that you just start a new project and includes the explosions code, if you reed the documentation included in the ZIP you can see that its fairly easy.

I'm glad that its use full for you who get it to work.. and I'm sorry, but there isn't much more i can do to help you with things not related to the code it self.
