My first clue...oh...I already said that.

In all seriousness, when I read that that the KMA Header was being updated (changed), and, that certain KMA imported trks needed to be "Converted," before performing any "Upgrade," I would have made a Complete BACKUP of my KMAs in case anything went wrong after the Upgrade.

This would include Backing UP any .Hst files, et cetra/ et all.

Come on guys, 4.0 was a M A J O R Upgrade!

Any and all problems reported since the 4.0 release, could have been resolved by going back to 3.321 and overwriting KMAs with the Backup KMAs. End of story.

With 20 years Computer experience, I'm sure you must have tried to see if your deleted .HST files were in the RECYCLE BIN.

It was MTU who made the decision to "support" VISTA, and, after 6 months, was still at it.

Oh, by the way, NEVER EVER discard a previous VERSION OF HOSTER, as MTU NEVER MAKES THEM AVAILABLE AGAIN.
