Redirection error when browsing to Bamboo pages

About a week ago, a test Bamboo installation I have set up on a Windows 2003 server started to have an error when trying to browse to it, both from the local machine it is installed on and remotely. I have also tried using both IE and Firefox. The error started when 1.0-rc1 had been in use for a while and still exists after an upgrade to rc2.

On thing that may be a factor is licences. If the test licences for beta copies last 30 days, it could be the case that the licence I am using has run out. However, the error doesn't give an indication this is the case and Bamboo still seems to be running build plans. The email with my licence key in it doesn't provide information as to when the licence is valid until.

When trying to browse to http://host:8085, IE gives an error saying "The page cannot be displayed". Firefox gives a more detailed error:

===============
The page isn't redirecting properly
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
