FreePBX

My Asterisk box crashed and hasn't been right since. The freepbx module doesn't work and more and I get this error message.

FATAL ERROR
DB Error: no such table

So I reinstalled freepbx in the packages section and I got this error.

Checking for PEAR DB..OK
Checking for PEAR Console::Getopt..OK

I do not know linux at all but from what I gather I should be able to tell Mysql to fix the database. Or is there anouther whay to fix it. Any help is greatly appriciated thanks
