You might be able to use your old CD key(essentially a certificate of ownership) to activate a game in steam. In that case you spending any money was unneeded.
I really donnot understand what you a trying do do, but sense that it is a waste of time. If you still have your CD key, than simply use it.
I bought my game from Gamer'sGate. I registered it on Paradox. That is why linking Paradox account to Steam does not work. BTW, Paradox has stated they don't use CD keys anymore.
But as regards the CD key that was on my Gamer'sGate AoD, that might work. But I don't know how to find it, and Gamer'sGate are out of business, right?
What I am trying to do Pang - SIMPLY - is install v1.12. But, OK, if you think that's a waste of time, perhaps I won't bother.
Actually, I will install it. I hardly am a quitter - especially when things get tougher. Or you never been in the marines?
However, it is nice to realize that the problems I ran into were there all along with no input from me. Now, maybe Paradox staff will find a solution. They have been very professional throughout. And as regards money spent on Steam, hey, I like to join that community anyway for MP sometime. So, there's far more issues than the simple way you paint it.
