It's good to know that PG keeps records back to 1999 -- even better if they'll provide a download link to software one can prove that he or she purchased way back when. I actually recall one time when I placed an order for an add-on program I forgot I already owned, and got an email back from someone at PG reminding me that I'd already paid for it. I mean, who else would do that? (I've bought software from other companies that you can download a limited number of times during a short time window -- while they try to persuade you to spend extra cash for a kind of "insurance policy" to allow you to download it again later on if you need to.)
I'll go ahead and save what I've got to a small, unused USB drive. Speaking of media reliability, I do know that at least one of my early PG-supplied CDs has gone bad (no apparent physical damage, yet it's unreadable when I try it in several different CD drives, as are a few other CDs I purchased or burned in the late 90s). So I may need to call PG on that one...
