Found it, but when I click and try to start a game I get massage "missing start.ini initializationm file"...
Do I need original COaS or only Maelstorm + mod (e.g ERAS 2)? I bought Maelstorm engine, but completly don't know how to install that, instruction is so unclear… #$%^%^#$. Where is that maelstorm.exe??? I got only some not working lnk… Jesus!
