I am so sorry you are having such a problem.....several others are also.

I found that when I got to the chat login page, it had some software for Digi that I had to click on. So when I clicked on it, nothing happened until I disabled my popup blocker. After that a 2nd gray page comes up asking if I want to RUN the software and once I clicked run, the login came up, I signed in and was in chat. That is why it is so important to know if there is a popup blocker on there somewhere that you are unaware of. I never knew I had one til the problems started. The WinXP popup blocker came as an update about a month ago.

Delete any Java that you have on your system and start over.....using the link above...

Good luck
