Cannot Open Kismet anymore.

[skuGen]

Hello, im currently working on a school project using UDK as game engine. Have been working on it couple of months now.

I have been using Kismet throughout this period with no problems so far, until now.

Suddenly I cannot open Kismet( by clicking on icon) anymore. When i press it, the blue topline of UDK(line above File,Edit etc) greys out, as if there is a window opened or something, but i cannot view the window.
Also tried using CTRL+TAB to get window open but without any luck..

Is there anyone who have an idea of what this might be? or what can cause this problem?

Regards,

skuGen

Try closing the editor, deleting UDKGame\Config\UDKEditor.ini and UDKEditorUserSettings.ini, then reopening the editor to see if that helps.
