Pbdirectory module error

I recently updated my FreePBX to and now the phone book directory no longer works.
My setup is Pbx in a Flash version 1.2 running asterisk 1.4
Asterisk Source version
Zaptel Source version 1.4.11
Libpri Source version 1.4.7
Addons Source version 1.4.7
CentOS release 5.2

In the module admin the phone book directory shows up as not installed.
When I tried to install it this is the error it gives me:
Could not remove old module var/www/html/admin/modules/pbdirectory to install new

Can I remove the files manually and try to reinstall?
