Hm. Its working for me...Try it again, maybe something was just wrong with it at the time.
If it still doesn't work, maybe it's because you clicked "Dont run", or "I dont agree/No" on a window that popped up on the first run. If this is the case, or want to fix this, Try refreshing your cookies (See below) then run the chat again. If a window comes up this time, say "Run", "Yes", or "I agree".
To refresh your cookies, in internet explorer, Go to "Tools" at the top, "Internet options...", go to the "General" tab, and click "Delete cookies". A window should come up asking to delete your cookies. Once you click it, it may take a few seconds, or even MINUTES to clear the cookies. Just be patient, and dont keep clicking on it - That will just lock up the computer.
If this doesn't fix it, you need to update some things. Try the above first, and then I'll Private message you a link to the downloads that may help fix the problem.
If none of this works, I'll get an expert to come help you guys.

Good luck!
