Ah yes, sorry. I remember now. Had the same, couldn't even open the index.html on my Mac.
In the index.html it says:
[quote:19w0m3hx]<!-- Note: running this exported project from disk may not work exactly like preview, since browsers block some features on the file:// protocol. Once you've uploaded it to a server, it should work OK. -->
That's why I embedded it in Phonegap and could preview it on the iPad Simulator.
I could also preview it on my iPad through the Live-Preview. Check the tutorials for this and don't forget to add the ports. I had to config port-forwarding to be able to see it on my iPad through my Mac through VMWare Fusion 6.
Works nice now.
(If this doesn't help than I cannot help you anymore )
