I am going to assume that you have Kotortool set to the correct paths of your game.
If kotortool crashes and 'loads-out' improperly, it may not record the 'last opened node' and 'treeview status' properly. Try disabling these options in the 'treeview' tab (options panel).
Also try to enable "show module descriptions/locations" and "build bif tree at startup".
JEDIJED has returned from the shadows.
P.S-What is that 'rookie' thing that changed from 'lurker' below my name?
