I am able toa ccess the internet, however, I used the address bar to request a specific www. Address, I receive a message that reads "the requested look up key is not active in any activation contant". I am able to use the Google home page to search for info. This is on my home PC, I do have a lap top and am not having problems with address bar when using it. Any advice will help.
