take a look in temp.html, if it's empty except for a bit of javascript and html to display the loading pic then something bad has happened. Either it's not been able to connect to the server, or it's been unable to write its stuff to temp.html in which case maybe it's got the path confused and is trying to write it somewhere that doesn't exist.
You could always try a reinstall, also good idea to install it as admin.
