I have bought GalCiv2:TA from 1C/Snowball (Russia) . Original English version with Internal code with which I have registered a snowball acoount and recieved registration for GalCiv2 on stardock.
As I understood it's a retail version. I have updated it to v1.96 by stardock Central Application but when I heard of update to v.2.0 and didn't see it in SDC I have installed Impulse.
Now I have GalCiv2:TA in v. 2.00.028, and GalCiv2 v.1.50.135 with available update to 1.53.136, GalCiv2:DA v.1.80g.100 with update to 2.00.104 but I can't update last two without valid serial.
