AsteriskNOW - 404 NOT FOUND

The GUI worked fine yesterday…but now I get the ‘404 NOT FOUND’.
I can http to the login prompt (GUI) and can login, it appears to cycle to the ‘System Admin’ page just before I get a "404 NOT FOUND’ page. Tried Firefox and Mozilla - same thing (404). I rebooted AsteriskNOW box - still get 404.

Any suggestions? Thanks.

One difference was today I changed my password as it suggested

Look at the html source and find out what is going wrong.
