OS 10.6.1 and Norton AV 11.0.3 still having problems

When I try to run LiveUpdate I get an error, "LiveUpdate is automatically updating your Symantec products. Wait until this process completes before using LiveUpdate again."  This happens every time, even just after a reboot.

 

OS 10.6.1 and Norton AV 11.0.3 and LiveUpdate 5.1.1.
