We do not have a "my.iscorecast.com". Your exported data should appear on http://my.iscorecentral.com
(follow the instructions under Options->Admin Website). If you are trying to get your games on the iScorecast.com server, and you did not have iScorecast enabled when you ran the game, you can go to Game Manager, select the game you want to send to the iScorecast server, then click "i-Scorecast Syncrhonize" (scroll down near end of Game Info view). This will send that game up to the iScorecast server.
