I am not able to duplicate the issue you reported. You did not enter your own ip to be excluded in the tracking_config, so there must be a file missing somewhere or your web host may not allow GEO Tracking, which is a very rare thing so I would count this out before I would anything. Just in case did you upload files using an FTP client? if so did you also try to upload the files using File manager of some sort through your cPanel? or Control Panel of some sort to see if it works then?

For extra precaution there is no MySQL errors inside either section of the tracker mod in the admin correct?
