Does it run when you link directly to the Exported folder after you upload it?
for example on my site linking directly to the exported folder:
http://visualparadox.com/games/pucked/
and I also have it in the Iframe:
http://visualparadox.com/games/pucked.asp
The iframe if you want to compare it with yours:
<iframe
src="pucked/index.html"
width="800" height="600"
style="margin-top: 5px; margin-bottom: 5px; width:800px; height:600px;"
frameborder="10"
id="game_iframe"
alt="game, app, application, play, puzzle, marble, coin, touch, ios, android, lite, pucked, games, apps, marbles"
title="Pucked">
<iframe closing>
Sounds like it might be your "src=" is the URL correct?
