xXWinterChaosXx : if you didn't backed up the dialog.tlk file, you'll have to reinstall. When you install a mod that modifies this file, make sure you back up the original .tlk file. Also read the readmes that come with the mods: they contain useful information. Make sure you don'tinstall a k2 mod in K1 and vice versa.
Darth Reavean: click on the list of the powers you already have and then re-click on "force powers" or "feats" to make them appear.
YertyL: not with KSE. You'll need a script here. Check this thread: http://www.lucasforums.com/showthread.php?t=131944
