Just one small edit to Bert's comment... to which I agree.
I would strongly encourage you to keep a copy of a much older version of the program (perhaps 3.6.12) as the current version may already contain the code that inactivates your computer from processing the program. And an older copy is the copy that is not under the term of the new EULA, too.
I am giving this advice based on no particular inside information. Bert, Vinny or others that understand programming better may have a better insight on which program might contain the code to deactivate Amazingcharts.
The problem with keeping the old copy is that the database requires tuning (probably means addition or deletion of old fields on Access though there is really no way of knowing what the tuner actually does). So if you are running a newer copy of Amazingcharts, your database may not work retroactively on a previous version. Thus, it would be helpful to know of anyone who has tried to run a Version 2 on a Version 3 database. If it works, great. But for myself, I'm happy running the old version of Amazingcharts in which I know I have legal ownership of the license, and hopefully avoid this potential legal issues associated with the program shutting itself down.
Of course, the way to eliminate all of this angst and discussion and guesswork is to have some sort of information from the Creator as to what is true and what isn't true. Otherwise, we wind up "Waiting for Godot." --pretty much an existentialist exercise, eh?
