Dear Hiroki,
I'm very sorry for the extremely late reply. Your follow-up question got buried in my inbox.
Since AntConc has been updated since your message, could you let me know whether you still need help loading tagged data with the current version? If so, please send a short sample of your tagged text and I will explain which indexer and settings to use.
I've now introduced a new system to keep track of my inbox, so I should be able to reply more promptly in the future.
Best regards,
Laurence
