first i came home and i jumped on the comp and click ko nd came up with "file has been deleted or moved, want to delete this shortcut" and so i deleted it and had no launcher so i did the bypass launcher thing and now it opens and dosent respond as soon as i open it any reasons why? im running 32 bit vista and yes iv tried running as admin

iv tried reinstalling and i open the launcher and dose nothing dosent say anything jst the launcher dosent say start or homeoage or nothing or options nor dose it update i tried manually updating but kept coming up with a error evertime i extracted. so i did i restore point thing and got to the prop i started with.
