"This bundle is invalid. The icon file Allie VS Shannon.app/LaunchImage-Portrait@2x~ipad.png must be in .png format."
This is the error I get when I try to submit my archive to the app store. It gets to the part where it tries to verify assets with iTunes and then I get this error. I've tried many things, and I know that this is in fact a .png file and not just named .png.
I have "compress png files" turned off because if it is on I get this error when I try to archive my app.

I opened up the image assets folder in finder and deleted the entries that were causing trouble (there was a duplicate "-1" image). Then i opened up my images in Preview and resaved them. Then I re added them to the project and everything ran smoothly! Now I'm waiting for App Store approval!
