I have been a loyal SoundForge user on Windows for two decades, and upgraded continuously until a few years ago I stopped at Pro 11.0 and switched to using other software on the Mac. I still want to go back and use it sometimes, though, via Parallels. The problem is now, that after recent MacOS upgrades, SoundForge wants to be re-activated. I used the automated system to get an authentication code from register.magix.net BUT IT DOESN'T WORK!!! All I get is a message saying the code is invalid, and there is NOTHING ELSE I CAN DO!! There does not seem to be any way to contact a real person for support at Magix via email, so I am hoping someone will read this and tell me what I can do to resolve this. My only theory as to why the automated system didn't work, is that I have MULTIPLE serial numbers in my "Current Serial Number" field, since I have upgraded multiple times in the past. Or perhaps the machine ID changed after a Parallels upgrade?? I no longer have a "native" Windows machine I can test this on....
