Really? Should I hide my copy under the matress? Perhaps put a bell on it? Odd, it's never disappeared before, the installation files can always be found in the same folders where they were orignially installed. The installation disc continues to be found exactly where I last left it. No disappearing act whatsoever. Not sure how a change in parental ownership of Nik Software would change that. But I'll keep a more vigilant watchful eye on things, just the same.
