I too have received this error "We're sorry, MSN Explorer has experienced an internal error and will have to restart." I have had 3 trouble tickets issued to Verizon DSL. The first told me I had a problem with my MSN Explorer program, and that I should delete the program and go to verizon.net/betterway and reinstall.
I did this, it took about 6 hours to install??? The problem came back about 4 days later. I followed the same procedure, and issued a trouble ticket. This ticket referred me to a different link for downloading, which I followed.
Again, 6 hours later, running fine. So, now it has been about 5 days, and the error has resurfaced. I purchased Spyware, have current updates on Norton, and need to figure out why this is happening.
When I submitted my 3rd trouble ticket today, I was told this is beyond the scope of Verizon DSL, and was a registry problem for which I needed to consult Microsoft.
How can I get rid of this problem once and for all?
One additional note, I have not downloaded Service Pack 2 for Windows XP because I was told there were still problems with it. Is this true? Does this have anything to do with what I am experiencing???
