[pc] Sith Edition Content?

[RQuest]

This might be posted already elsewhere.

But since I did´nt find it with the search-tool....

 

How can I access the Ultimate Sith Edition Content.

I played the "standard" Levels till the End.

Killed the Emperor.

Restartet the Death Star Level and killed Vader.

 

Now I got the Jedi-Robe and the Asassin Robe BUT the extra Levels aren´t starting and there is no possibility to set them in the Mission Select panel.

 

Please tell me I don´t have to play the Game in whole again...

I just want to play the remaining three levels.
