I've come to the conclusion that "Invalid module format" means absolutely nothing, accept that it could not do what it was asked to do. It's just another useless error that has no specific meaning or cause. So "invalid module format" should be ignored and translated as "I could not do it". There are many posts on the internet that say that it means this, or it means that, but the truth is that it means nothing other than the fact that it failed to do what you asked it to do.
