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.
