Zip/Attach a copy of the original Hand history for the table with the issue*
*All original hands that are auto-imported get moved to an archive for performance reasons. Your \HM3Archive is in C:\HM3Archive by default, but you may have put it anywhere. The archive should be organized by \Network\Month\DayOfMonth (example: C:\HM3Archive\SiteName\HM3Archive\2016\07\31). It is configured in the Tools - Settings - Import menu.
* When sending any files please zip them (select all files with CTRL+A > right-click > send to > compressed folder) before attaching them to an email. If the attachment is larger than 10MB please upload them to a file hosting site like https://wetransfer.com/ and copy/paste the download link directly into the support ticket email.
