How do I test the work-in-progress game?

I'm new to Construct2, and so far my only 'game' is a spaceship flying around a race track by using the mouse or (hopefully) touch controls. The problem is it works fine on the computer, but when I try to test it outside Construct2, all I get is a black screen. Anyone know why?

Thanks, any help would be greatly appreciated. :)

(btw first time I use Dropbox, so I hope you can open the folders. Let me know if it doesn't work, ok? Again, thanks.)

It looks like you have put you files into private DropBox folders, at least I am unable to open either

Sorry, I'll see if I can change that later today. Thanks. :)
