AteriskNow beta 4 problems

I am a long time user of both Asterisk and the now Trixbox. I have been following and experimenting with AsteriskNow. I made some manual changes to the extensions.conf file to try to get some dial plan changes and when I was finished could no longer log into the GUI. When I try to log in it just moves me over to the setup wizard login but that is as far as I can get. If I do get back to the GUI screen everything is blank, although all of the system is up and running even after a reboot. Is there a way to recover and log back into the system or do I have reinstall.
