Vegas 17 on my laptop is continually revoked saying I have changed my hardware. It does this every time I shut it down and start it up. Many thanks to correct. Annoying in the extreme.
Uninstall VP17, and go to vegascreativesoftware.com / magix.com, log-in to your account, and 'My Products' section, Deactivate. - Reinstall VP17 and re-activate.
