Hello,
As per the Logs, we see the below errors:
2013-07-26 09:03:01,004 [pool-124-thread-11] ERROR rcl.FtpHelper - Error in deleteFile :
java.net.SocketException: Software caused connection abort: socket write error
at java.net.SocketOutputStream.socketWrite0(Native Method)
at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:109)
To recover the LUA interface, re-launch \Program Files\Symantec\Live Update Administrator\Tomcat\bin\bootstrap.jar.
After running that, the LUA interface will appear when launched.
