iOS v1.6 may not import ezWinScore PSS.txt file. Work around is to use device with prior version, or Android with current, and then synch.
A fix for this was submitted to Apple. If you have trouble and do not have access to any of the work around configurations you can use clubs.practiscore.com to import and synch a new match, or email pss.txt file to [email protected] for us to build a match (try to do that before it is urgent).
