Patches for Original Sins of a Solar Empire

Hello people I'm a newbie to this forums ( Always wanted to be e Newbie )

Well anyway im a bit in gaming rush ,installed some games bought some games and am still not ready

But i also installed the original SINS and wanted to update it but i only can find the 1.05 patch and their i a1.1 so i'f read

Now i remembedr something about a online client( sort of like steam)  but i forgot about it ( was a wild night with booze and other substances ) so a sort of client installer

 Anyway its hard to find anything for the game. mostley because there are three(?)  sequels

Anyway help would be appreciated
