thanks for the nice welcome and let me use this thread for a question right away.
I'm sure, I'm just not seeing the obvious, but: how do I register the game?
I admit I rarely register games/software, only if absolutely necessary, but for this game it's probably worth it and I do need it.

I installed it, downloaded the patch etc and it's working fine, but: in German -and after the patching- in quite some mixture of languages which is somewhat annoying (even though I've seen games that were MUCH worse translated)
Anyway: I want to follow some advises I found here in the forum: to uninstall the game and then Download it again via SDC to have a pue english version
But I guess for this I should have registered the game.
I know I entered the serial number once when I installed the game, but to test if its already regisrtered I used the service to send my serial number to me via email but it wasn't in the email and it was written that if there is no serial number in it, theres no registered software connected to my account.
Alright, to make this short: how exactly do I register the program now, I haven't fund any option for this in the game or at the startwindow that opens and I also haven't seen any obvious link to some register page on stardock or galciv2-page.
thanks in advance if somebody can direct me to the solution
