I've spent an hour searching on this subject, can't find the answer.
Using version 2.17.01g
Running everything as admin (using VISTA)
Have region set to US
Seems to start ok, finds the file and says something like "starging to import 15 hands" or whatever and always ends with 0 hands imported. Always has error message beginning with the text:
"Unable to get the tournament ID for tourney game number -2090385070...1.00 NL - Tournament) Real Money ..."
And I am importing NL cash hands, not tournaments.
