can u tell us what operating system you are using (windows xp,98 etc): XP Home

also detail exactly what you are doing
and does problem happen all the time
is it with certain sites : I can access most web pages fine, but when its a site where you have to sign in (eg Halifax / Paypal etc) I can get the home page no problem but I get the following message when trying to log :
The page cannot be displayed
The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings. "
As I say its been like this for 3 days now.

When trying to access MSN messenger I get the following message: Sorry, we could not sign you in because the sign-in name you entered does not exist or your password is incorrect.

Ive not installed any new sotware/hardware and I know I am using my correct MSN sign in details

Jim, Yes im on B/Band and yes ive tried resetting my cookies

Thanks for the help chaps
