Update the plugin, check out the config file to enable database support.
By enabling database it will disable flat file which means you will lose your current poke counts. Sorry there isn't much I can do about this without a lot of work, maybe in the future I will add the ability to migrate from flat file to db.
Database support has only been tested with a MySQL database with
utf8 character encoding, other database types and character encoding may not work, please let me know if you have issues!
