If the message you meant was:
"Server is running but cannot find SWTOR client"
This means that the server piece does not see the SWTOR client window couldn't be seen on your desktop. The most likely reasons this is occurring are either that your game window is minimized or perhaps you changed the Window Title and Window Class settings in the server configuration. You can try taking the defaults by blanking out both of those fields.
What game are you trying to use this with?
