When trying to log into Lycos SMS as well as adding bets to a beting slip at williamhill.co.uk (only on long selections i.e. 10+ footy matches) my PC brings up the error after about 20secs: Page not found.

I know Lycos SMS works fine as I've tried it at work. The thing is I could access the site about a week ago no problem, but now it's hopeless. I've also reset the Internet options to no avail. At present I'm running Windows 2k Pro and IE6.

Any ideas anyone?
Many thanks.
