Reading the KSE readme might be a good idea ;)
    Symptom: After leaving the Endar Spire or Leaving Taris, you run into a sequence
 where you should be seeing a "dream" cutscene but instead you're locked up in a 
 room with a "CutStart" object that doesn't do anything. 
 Cause: You have NOT placed the modified .dlg files into your override directory 
 and you have changed your character to a Jedi/Minion/Droid class or you have
 changed your Gender to something other than Male or Female. 
 Fix: Download the KSE Fixed Cutscene Files (available from 
http://www.starwarsknights.com/tools.php) )
 and place the .dlg files into your Override folder.
