Bear in mind that even _with_ a presumably safe, non-recalled VF kit, taking a fall on a via ferrata route generally is significantly more dangerous than a Leader fall in belayed sport climbing. I've actually seen somebody get hurt in a fall on a difficult VF route.
It's important to work you up progessively thru the difficulty grades, not get into a route that's beyond your ability. Falling is a bad idea.
