A while ago, I decided to load up EV Nova again, having not played it for some time. I definitely remember registering it, as I had played through one or two of the campaigns without registration hindrance, and also played some mods for it. However, that was back on a different computer, and I couldn't find the registration details.
No matter, I thought, I'll use Ambrosia's license code recovery service. But all they had on the database for me was Darwinia, the most recent product I registered. I know for certain that I bought keys not just for EVN, but also Harry the Handsome Executive (I have screenshots from towards the end of that game), and I'm pretty sure I registered both the earlier EV games as well, as I've used plug-ins with all of them. There may be a couple more games I registered over the years that I've forgotten about, as I first got into Ambrosia games a long time ago. (Some of these might have been registered by my father on my behalf, if I got them when I was too young to have a credit card, but EVN is too recent for that.)
Anyway, in my disorganisation I don't have good records of what I did and didn't buy, and as far as I can tell, neither does Ambrosia beyond about 2 years ago - but maybe I've entered the wrong keywords or something.
Does anyone have advice in this situation beyond 'buy new keys'?
