Samuya, accordin to apple Invalid Binary means:
Invalid Binary - your binary has been received through Application Loader, has been processed, but did not meet all requirements for upload. Examples of an invalid binary are: your binary icon does not meet our requirements, you have placed the payload directory at the wrong level in the .app wrapper, you attempted to use a non-increasing CFBundleVersion, etc. You will receive an email if your app is in this state, detailing what you need to do to fix your binary for re-submission.
i think you messed up the icons as most likely thing (and yeah i know it's very easy to do) or you have zipping problems as i told you before. I hope this helps you further.
