This morning I was able to download iMovie, iPhoto and iBook Aurhor without getting this error: Failed to verify the preflight file. It is not signed by Apple.

 

However I am still getting this error when trying to update Numbers, Keynote, Pages and Aperture 3.5. I am starting to think this all maybe caused by a server overload with Apple.

 

Anyone else receiving this error: "Failed to verify the preflight file. It is not signed by Apple" when trying to update Aperture 3.5?
