MBII Client isn't supposed to work yet, because you moved "rd-vanilla-mbii_x86.dll" out of GameData and because "rd-vanilla_x86.dll" is in GameData. But you should be able to play via "openjk.x86.exe - ярлык" while having Launcher running in background. And this bugs me the most... Very weird... The game started as MBII and literally switched itself to japlus... wtf?... The only logical explanation I can think of is messed up configs. So once again, move these files to some completely unrelated location, or just delete them: Jedi Academy\GameData\MBII\openjk.cfg C:\Users\****\Documents\My Games\OpenJK\openjk.cfg And search for "openjk.cfg" in folders as well, look into as many folders as you can. Then start MBIILauncher and "openjk.x86.exe - ярлык".
