here's a novel idea... dont delete the files, and if you used a subscription cam to program it and havent been paying for it, pay for a month to make small edits/repost, then stop paying again?
I have a better solution - for me at least - I just keep the old software running. It does everything I need or will ever need.
You know they are only going subscription because all they have to offer now is dark screens, which is annoying shit anyhow. If they had any real improvements, then people would continue to buy newer versions and none of this would be an issue.
