I have WinX HD Video Converter Deluxe from a previous giveaway three or four years ago. It, too, was a ‘lifetime’ version. Worked fine.
I fired it up again a few days ago (I use it about 3-4 times a year), it went online to its web site and offered me a paid update to a “full” version. When I declined the offer, it closed the browser window, then it closed the program itself which was running on my machine. I tried it three times, it did that three times.
Massively obnoxious behavior. So much for “lifetime”!
So I went to my firewall and turned off its online access. Then it loaded and ran fine.
I no longer trust Digiary Software.
