I used to have this problem as well as I am also with AOL.
I was able to read and send e-mails but whenever I tried to load a wabsite from my favourite list I kept getting the 'page cannot be displayed' error.
What I did to cure the problem was change my cookie controls to medium-high.
I also reset the web settings at START > SETTINGS > CONTROL PANEL > INTERNET OPTIONS > PROGRAMS.
Also I delete ALL cookies, temporary internet files and history and then logged off and reset my PC and logged on again and I have not had the same problem again (touch wood!)
