You are blocking cookies. That's why you can't get into sites. Try this experiment: turn off your software that blocks pop-ups and cookies. Then go to a site where you haven't been able to get in, and click on the link. It should let you right in, if your pop-up software is no longer blocking pop-ups and cookies. Now try setting the software to a minimum block, and keep increasing it, testing it each time, until you reach the point when you can no longer get into the site. Then decrease your protection by that amount, and you'll be able to get in. I have the same problem when using AOL, because of it's new security. But when I minimize AOL and go through Internet Explorer, I'm asked if I want to allow the cookie... Let me know if this helps.
