Chat bug, "this movie is causing adobe player 10 to run slowly"

I've tried everything, from using IE, to Firefox, SO today i decided to change computers, to see if that was the problem. I got on my brothers brand new out of the box computer to see, figuring the problem was my computer, but i can't get into chat on his either. EVERY time i log in, it loads, authenticates, shows the messages before i got there, then stops, freezes, and a message pops up saying "a script in this movie is causing Adobe Flash Player 10 to run slowly, if it continues to run your computer may become unresponsive"........ This is the 3rd computer, and 4th browser that i've tried. I have windows XP, and my brother has vista, and neither works. I'm wondering if something is wrong with my membership or something? something like that? maybe i could change my ID or something to like tanker67 leave out the underscore? i dunno, let me know what you guys thing is going on.

Dunno, dude. I just logged in using Win XP 64 and Firefox 3.5 and it not only works for me...but all of the other people in chat.

Could be your network.
