locking IP-address

I am using phpOpenTracker (version 1.5.0rc1), but there is one thing i
can''t get working. That is phpOpenTracker excluding me from
counting. Because i use a shared host i visit my site as a regular
visitor, but i don't want to influence my visits with the total stats.
This is what i thought should be work:
- In \conf\phpOpenTracker.php i edited this line:
$PHPOPENTRACKER_CONFIGURATION['locking'] = true; (It should be true i
think)
- In \conf\lock.ini.dist I changed the name to lock.ini and added this line:
ip_address #80.60.207.159# (This is my IP address). I also tried host
#80.60.207.159#.

But still my visits are logged and appear in the stats page. Did i
something wrong? Please give me some tips.
Thanks
