It seems that once a new update is announced, the old ones become unavailable. If that's true, the we should keep all the former firmware updates.
Ok, for an update. The old firmware was still available on the Nikon website. I was able to download it and reinstall it in the camera. (the first time I tried it it didn't work). It did reset all my settings in the camera so I had to reset everything in the camera but my Viltrox lenses now work so I am not updating again until that issue is resolved. Thanks everyone for your replies and help. Hope this helps anyone from who was thinking of installing the update and who has some Viltrox lenses.
