Three days ago I got the revised 18.5 patch and everything was working correctly until this morning when I did a System Restore. Before I did the restore I disabled Insite Protection, ran system restore which was sat and reenabled Norton Insight Protection. Rebooted and opened up NIS and noticed that the Intrusion Prevention Tab was Off. A One Click Support box opened up and displayed the error>3040, 20011. Rebooted and the same error appeared. The solution provided was to uninstall and reinstall NIS which I did by removing NIS 2011 from the Add/Remove, running the NRT twice and reinstalling 2011.
NIS 2011 is back up and running ver 18.1. Guess I will have to wait for the 18.5 patch again. Don't understand why I got that 3043 error after doing a System Restore because I have used the restore feature previously with no problems.
