I regularly visit one website. Recently I have been getting the message "Page cannot be displayed". Is there anything I can do to get this page to display once again. Problem only occurs on my computer, page can be accessed from others.

I have not changed any of my internet option settings, (all the settings/cookie options  that allowed me previous access are intact) and on a few occasions i am redirected from my requested page to a casino webaddress. Could the problem be caused by this site trying to redirect me to them?

I have no problems browsing or connecting to the internet except for this one company website. I know the site hasn't been moved so why does it time out?
