*Try creating a new UTF DB - http://faq.holdemmanager.com/questio...elete+Database
*Now import a small portion of your \HMArchive so you can see if the problem exists in the new DB - http://faq.holdemmanager.com/questions/98/How+to+Import+%26+Export+Hands
*If the new DB seems to work properly, you will want to import the rest of your archives to the new DB, export/import the hands from the old DB to the new DB, and export/import any player notes and tourney summaries - and then delete the old DB.
*Make sure you export/backup everything before deleting the old DB - http://faq.holdemmanager.com/questions/372/Reinstalling+on+a+new+PC+-+Backup+Tips
If you continue to have problems, please zip and email the problem hand histories, with a link to this thread and your forum name, to firstname.lastname@example.org
All original hands that are auto-imported get moved to an archive for performance reasons. Your \HMArchive is likely not in your \Holdem Manager directory. We normally suggest you use C:\HMArchive, but you may have put it anywhere. The archive should be organized by \Month\DayOfMonth (example: D:\HMArchive\2009\07\31).
