Hi Trawlerman

I had some issues also with Norton Security Prof.2004 as a general matter... Had to change it with Zone Alarm...
But it seems to me that your data base is huge. Try to store your covers on an external file first if you have not done so yet.
Then try to reinstal Norton. Log in with your administrator rights and under the programm control tab, set OCD for automatic access to the internet.( trusted Zone).
If that does not work try the Norton web site for FAQ's and /or send an email to their tech support.
Good Luck
