Hi johnmcenroy,
the new 195.php contains more information about the Country classification than the old 195.php.
I'm not really sure but I guess that is not a big problem for the Stat.
Is it possible for you to live without the whole new funktionality of the Country classification from Version 3.0 - try it!
But - one question from me to your file size limit:
If you run the Stat on your Webspace it will collect all information about your visitor and save it in a file on your Webspace. And this file will rise every day!
Maybe, it doesn't take a long time to come close to your limit of 500k - what will you do then????
Best regards
