Make sure you are using IE and NOT Firefox--firefox won't allow a lot of the plug ins and kinks of chat to work right... and sometimes has caused users to not be able to get in.

Make sure you have java, flash players, etc.

As Torq said, clear ALL your history in your IE browswer, close it, shut your computer off and re-boot.

If none of that works, send me a PM, I'll try and help you out more.
