Maybe when OD Crashed the sdmcp.exe became disabled ? I'm not sure what you mean by Sys tray is empty on OD because I have that removed anyway...but if you mean the icons that appear in your task bar sys tray are not showing in your OD then check to be sure your sdmcp is enabled ...you can make a shortcut to it or enable in in Stardock Central or download the sdmcp.exe at the link below.
1-Open C:\Documents and Settings\USERNAME\Start Menu\Programs\Startup
Add a shortcut to sdmcp.exe there.
2-Under tools is SDC you can check off to enable MCP smartstartup.
Download Sdmcp.exe here
