look for the file:
c:\program files\common files\stardock\TrayServer.exe
if you don't have this file, email support@stardock.com explaining the problem (reference this thread if it helps). without this program, the system tray will not work in DX or OB.
if you do have this, have you tried rebooting? you need to do this after installing OB or DX for the first time to get the system tray to work.
