Site Access Problems post-update

Hi, first time user and non tech-expert, so please be gentle!

Recently had 2 updates for the o/s - using Vista Ultimate. Since the update, I can't access a particular gaming website I frequent - all others are fine. I've tried different browsers - IE, Firefox and Chrome (my default for this site) - to no avail.

I've looked at Firewall settings etc, not getting any joy. Any ideas?
Any help appreciated.

Uninstall the updates. Reinstall one at a time, and try it for a while. The problem may not happen again. If it does we know which update was that caused the problem. It may not even be an important one. You do not have to reinstall it.
