I upgraded from Vegas Pro version 12 to 18. After registering and using version 18 a few months, I had to start registering again every time I open Vegas Pro; each time I get wonderful notifications that a new version is available. I probably re-registered over 300 maybe closer to 3000 times. I would like to use the software I purchased and registered without having to go through this every time. I have no desire to ever upgrade if this cannot be fixed; I'd rather just go back to version 12 instead. It's important for security reasons and system maintenance reasons to keep my Windows editing computer offline. I don't need Windows updates to break my system if it's working properly. Registering requires connecting to the internet each time. Please advise.
