I omly have a backup of the last version that ran fine. Don't have one from 3 years ago before they put some king of encryption on it to lock it to one PC. Even though, they should respond.
This sounds like some sort of Grade A conspiracy nonsense. I can (and have) copied my DSD+ folder to a USB stick and then run DSD+ on all of the laptops and netbooks in this household. No problems using an Airspy (which doesn't need Zadig's intervention, so very easy to test on any Windows PC) to monitor whatever is out there. DSD+ doesn't need to phone home to run - I use it mobile on laptops with no Internet link, so your theory doesn't pass the sniff test.
Sorry but your advice sucks, really thinking I might get some professional advice.
Just backup to something I don't have, you sir are the problem in today's society.
If that's how you communicate with them, I wouldn't blame them for not dealing with you. But I doubt that's what's going on. They obviously care about what users want / have to say - I've seen enough reports posted here of issues that were then addressed in later updates. You emailed them what, once? Why don't you just try again? And how do you know that they didn't respond? It could be blocked as spam. Have you checked?
Looking like they made their money and going bye bye now.
So a couple of recent updates means it's a dead project? Yeah, ok...
To be honest, you're sounding as bad as that guy who got his scanner damaged by shipping it in a bubble envelope and then blamed everyone else. Now feel free to tell me that my advice sucks and that I'm the problem in today's society.
