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 (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 dropbox, then click 'Share' > 'Create Link' > Copy Link' and right-click > 'Paste' the download link directly into the support ticket email. If you have any problems with dropbox try using filedropper.com or google drive.
