Just a curious question. Don’t you test the app first with a development certificate on your own device?
I almost always test with an AdHoc profile. In fact as a good example in another thread, the app had a corrupt .png file that png_crush was crashing on excluding the files. The development profile doesn’t run png_crush.
I don’t get any errors when testing it and have tested it on the latest gen ipad, all work just as expected when testing with no errors. My last build was on the 5th so it was with the latest public release build. I test it on my own device with a development profile.
Rob could you tell me where i could find that other thread as that seems like the only other thing it could be. I am thinking about using a new certificate and setting it up on itunes as a new app as that is the only difference between the tested app and the itunes version.
I have now tested it using an adhoc profile and it isn’t working properly, it shows the same way that it does from itunes. so think it could be a corrupt png file like you suggested.
After looking at another thread i have seen that when i build i have the error not a png file come up, which seems like an easy fix, then hopefully that will solve the issues.
I have now fixed all the images, and it is all working just as it should!! :D :D 
Thankyou for all your help and patience with a newbie
