I have Norton 360 6.0 and have the same problem.

I am in here by accident.

I searched in google about this  Word-message.  Than I found a KB from Microsoft.

Per accident, I saw at the foot of the message a notice about Norton ! ! ! !

So I searched in google again - but this time about the message and Norton.

That's how i came here :-)

I,m not shure about causing other problems too....   I don't trust Norton anymore....

But now:  The 30 days - money back option is gone for me.....  (**bleep** wat drop :-)
