Xcode 4.5 - CopyPNGFile persists. Need new ideas

I'm making an iPad app and it runs on the simulator, but fails when i try building it for the device.

the error is below:

enter image description here

These are the things i've tried to rectify this issue:

went through every PNG file with Photoshop and saved them again w/o the interlace
Deleted all the images in my Resources folder and added them again by dragging/dropping the images again
Deleted ALL PNG images (left the JPGs) and it works...when i add one PNG, Xcode throws a hissy fit.
Deleted the derivedData in my ~Library/Developer/Xcode
quit Xcode and tried again
restarted my computer and tried again.

i tried checking about the paths, but i'm not sure. Any ideas would be great please.

Addendum i also want to add that Xcode is throwing errors against its own [email protected] and Default.png!

Solution

This has NOTHING to do with png files missing but with a dynamic library you are linking against which isnt available on ios
