Problem installing / config Tripwire

Hello. Trying to install Tripwire but doesn’t make it work. But only gets this mis-resubparting:

[julle@HaxBox ~]$ sudo tripwire -m i
### Error: Invalid input stream format.
###
### File: /etc/tripwire/tw.cfg
### Configuration file could not be read.
### Exiting...

the tw.cfg file looks like this:

@@section GLOBAL
TWROOT=/usr/sbin;
TWBIN=/usr/sbin;
TWPOL="/etc/tripwire";
TWDB="/var/lib/tripwire";
TWSKEY="/etc/tripwire";
TWLKEY="/etc/tripwire";
TWREPORT="/var/lib/tripwire/report";
HOSTNAME=localhost;

@@section POLICY
TWCFG="/etc/tripwire/tw.cfg";

Some one can help me out?
