Internet Explorer error...

"Internet Explorer cannot open the internet site *address*
Opeartion aborted"
First, I should explain that I'm using AOL 9.0. I know I shouldn't be using AOL but I'm stuck with it I'm afraid. :'( I use Firefox to browse the internet so I don't get this problem, but my parents use the AOL software and they can't access any of the AOL pages (e.g: News, Chat, Shopping etc.) Other pages work fine. I've tried to get them to use Firefox instead but they're refusing. I spent most of last night searching for a fix but didn't find anything and I'm not even going to try and ask AOL for support. I've recently uninstalled Comodo Personal Firewall so could that be something to do with it? If anyone can help at all then please please do! I'm getting alot of stick about this and the last thing I should be doing right now is trying to sort this so I'd be very grateful for any help.
Thanks
