Is this for cash games or tournaments? We have a guide for getting things setup with Microgaming
here however only tournaments are supported at this time. Cash game hand importing is disabled as Microgaming have decided not to provide full hand histories in cash games when you have not contributed to the pot. See
this post on the Microgaming site for details and
this thread for more information. Since Microgaming has not made this change to tournaments, we will continue to support Microgaming tournaments as long as hand histories are written for every hand.
