I've installed the TD Desktop on a fully updated Windows XP PC. However, when it starts up, the cloud and network icons are lit, but not the authenticated icon. Then after 10 seconds the network icon goes dark. Then if I complete and click either the signup form or the login form, the cloud goes dark and I get an error at the top that reads "request timed out. make sure you are online." Any idea why I can't connect? (screenshot at http://twitpic.com/1vaqj2)
