Remove my IP from the blacklist?

Hi, I downloaded a trial of your IP filter.  I was testing it out and added a couple of countries like China.  Which seemed to work great.  I then went to the IP address's tab and added an IP address to it.  I thought I was whitelisting an IP address, but apparently, it black listed all other IP addresses.  I could no longer reach the site.  I logged on via FTP and deleted the plugin from the plugin directory and restarted the machine and was now able to get to the site again.  I have tried to reinstall the plugin from a new download and there is some configuration file that is not stored in the plugin's directory, so if I reinstall it,  it automatically loads that file and blacklists everything.  Do you know what I can do to fix it, so I can reinstall it?

update Setting
set Value='False'
where Name = 'ipfiltersettings.enabled'

This SQL code will disable plugin.
You will be able to enable it on plugin configure page.
