Can't find contactinfo.conf

I am having a new problem with beta 4. I had a power failure recently and when the system came back up, I can login but going to the users tab I get a message can’t find contactinfo.conf and then gets put back to login. If I login and go to any other tab there is no data? Any help?
After looking into /etc/asterisk/ I cannot find the contactinfo.conf file. Can it have been deleted by the reboot? How can I recreate it without rebuild of the entire system?
