Both my computers are getting the same error message when I go to my
homepage with Internet Explorer.  Message is shown below:

line b problem parsing xml: 'nul' is nul or not an object

Now I can tell a little bit as to what the problem is, but more important...
is anybody else getting this?  Is it the result of MS Update that was
installed?

What can I do?

Thanks in advance.
