Sonar Protection "Off" Computer "At risk" notification

For the last couple of days I have seen NIS 2011 showing "At risk, Fix now".

 

When I do so, Sonar Protection runs but then informs me "Not Fixed".

 

I then find that in "Settings" Sonar protection is listed as "Off" even though I had reset it to "On", prior to the running of  Sonar Protection.

 

Can anyone help me with this please?

 

Windows XP Home edition SP 3, IE 8, Intel i3 CPU, 2.93 GHz, 1.86 GB of RAM, NIS 2011 Version 18.1.0.37

 

I also have Win 7 Home Premium 64 bit, IE 9 Beta, NIS 2011 Version 18.5.0.125, on a separate Hard disk,  which has not incurred any problems, unless this is in some way affecting my Norton program on this OS, which, I presume, is unlikely.

 

IE 9 Beta appears to work perfectly with NIS 2011 except on these Boards, where I can read postings and give Kudos, but cannot make or reply to postings.  Hence my use of the XP OS when writing, as now.

 

Cheers,
