In general, I climbed a couple of days on the thematic forums, I still did not find a solution to my problem.
1) Invalid key (most likely this is due to the then distributor of the game in CIS region "Buka", and from this all the problems)
2) Сonnecting to Conflux (can you please not write about the connection, provider and ports, I have been fighting this game for 2 days)
3) Black screen, languages and other minor issues (the game starts and only works in windowed mode, the inability to change the language, in any way, neither the registry editor nor the replacement of files helps in any way)
Everything ... all this is very upsetting, why did I remember this game after 10 years...
Maybe download the game from "those sites" as many advise?
This is all to the fact that my Uplay version of the game is simply not working
(version 2.1.1 shades of darkness)
Waiting for answers, until then, I'm going to play HotA)00))0)0
