Ah, OK, that would explain it.
I would recommend updating to Beta 15 and re-importing your hands.
1. If you still have all the original hand histories in the 'move processed files to' folder, great,
1a. if not.... you will need to Export your hands from PT3. Database -> Database Management, select your DB, click Export and save them to an empty folder somewhere - note where this is.
2. If you have a registered copy of PT3, create a new database (DB Management again, click New), and set it to Active and Default.
2a. if not... you will need to Purge your database to empty it (again, DB Management). MAKE SURE THE EXPORT WORKED BEFORE YOU DO THIS, as you can't get your hands back afterwards.
3. Once you have your empty database, use Manual Import to import the HH files prepared in 1/1a.
Download and install PT3.
Please read the
Beta 15 release notes first.
