I think something is wrong with the build -- when I load the .pdx in the simulator I get a "Couldn't find pdz file main.pdz" and if try to sideload from website get "The bundleID field is missing from pdxinfo."
With any luck this should be fixed for you now! I've re-uploaded a .pdx.zip file with a valid pxindo in it. Verified this works, for me at least, via the website sideload
