hmm seems like all my Windows programs (IE8 and WLM) seem to have no internet access too. I mean they did, until today. Ive tried all the obvious things but I cant get it to work. Im looking into this myself and will let you know if I cant fix it.
Like you my Firefox and my games do have internet access.
Anyone know of quick fix?
******FIXED******
evidently this happens to a lot of people and it has the stupidest fix (just worked for me)
Control Panel > Network and Internet > Internet Options
Under the "Connections" tab theres a button "LAN Settings" click it and tick the box "use a proxy server for your LAN" and "ok" out of it all. Then go back in and untick the box again.
lol Im not kidding this worked for me
