install_amp access ip

Hello, I’ve installed FreePBX + Ubuntu Server 11.04 + Asterisk but I’ve made mistake with the configuration in install_amp. Everything is working but when the install_amp menu asked me to enter the ip address for the admin panel I entered and now in the end of the installation it says “Please update your modules and reload Asterisk by visiting”. My question is - how can I change the access ip address of the admin panel because when I try to open it it says “Forbidden - You don’t have permission to access /html/admin/ on this server.”. Can I change the ip or can I do install_amp again with the wizard ? Thanks in advice !
