AppleTV - ITMS 90013 - Corrupt image file

Hi, I am receiving the above error after trying to upload it to the App Store.

I would know what to do IF Xcode would provide WHICH file is corrupt.

The error reads:

ITMS-90013: Corrupt Image File - The image file $[IconName] appears to be corrupt.

Again, I would know what to do if I had more information about which file(s) to fix.

Could anyone FROM APPLE help me or give me a hint?

Thanks, Dan Uff
