I have recently been getting the following error message when trying to purchase items via the internet on secure sites. "This page cannot be displayed some sites require a 128 bit connection security"
I use windows 2000 with internet explorer and my isp is bt/yahoo.
Can I change my connection security and if so how do I do this. Could it be linked to a change in telephone operator - I could access secure sites before.
I am very new to computers and the internet any help would be appreciated.
