tutorial02 mesh problem - help much appreciated!

Hi -

I've been following the tutorials for sio2, and I quickly hit a problem with exporting from Blender.
I've been investigating this and that for about a day, but I'm getting nowhere I'm afraid.

When I run tutorial2 with my export, I get this result (screen shot from iphone simulator)...



But in blender, my scene looks correct. If I use the .sio2 file from the SDK in the same xcode project, the iphone simulator shows the correct result.

Any ideas?....I'm new to blender and SIO2 so quite possibly I've done something stupid...let me know if I can provide more info.

Many thanks!
