'Is not a valid HM3 database'

[Pokerplayer!]

Hello,

My database runs on an external harddisk. For some reason the harddisk disconnected while playing on pokerstars. When I try to restart my database now, it says my database 'is not a valid HM3 database'. Already restart my computer several times but no result unforunately.

How can I restore my database?

With kind regards,

Are you playing on a MAC using Parallels or some other type of Windows Emulator? I typically see this from users on MAC/Parallels:

Holdem Manager 3 requires the \Documents folder to be a local folder and not a shared folder.

To use HM3 with Parallels, you have to disable shared \Documents folder between OS X and Windows.

Please follow the guide from their website with possible solutions:
https://kb.parallels.com/en/112983

Specifically:
2. Isolate Windows from Mac to exclude Mac OS X influence. (Virtual Machine > Configure… > Options > Security > check on Isolate Mac from Windows)


If that doesn't apply or does not help:

Please close HM3 (if it is actually running) and the HM3 Server and rename the database file - C:\Users\{UserName}\Documents\Holdem Manager 3\Databases\{DatabaseName}.hmdb - to a different name.

Now when you start HM3 again it will start the setup wizard so you can create a new database.

Please do not create your HM3 Database in a sub-folder of any cloud file hosting service (Dropbox, OneDrive, Google Drive, etc) as it can cause database corruptions because it will constantly be syncing the database to the cloud while you are playing/importing.* You can configure HM3 to archive any auto imported hand history files to a cloud file hosting service folder if you choose to as that will not affect the SQLite database in any way, and you can obviously store any HM3 database backup files you create in a cloud folder instead of the default path HM3 suggests when backing up databases.

If none of that helps:

a) Please create a support ticket via the 'Contact Support' (https://support.holdemmanager.com/support/category/19) link with a link to this thread and your forum username. Please reproduce the problem and attach a set of log files (https://support.holdemmanager.com/support/faqView/Holdem-Manager-3/194/How-to-send-HM3-log-files-to-support) and a screenshot and detailed description of the issue in the support ticket you created.

b) Please send us the actual database for testing.
- Close HM3 and right-click - 'Exit' the HM3 Server icon in the Windows Notification Tray.
- The *.hmdb files are saved by default in C:\Users\{Username}\Documents\Holdem Manager 3\Databases
- Make sure you also include screenshots of your reports/filters and a detailed description by tournament number, session, hole cards, filter, stat, etc. of some of the errors we need to test.
- When sending any files please zip them (right-click - send to - compressed folder) before uploading. Please upload them to a file hosting site like dropbox, then right-click - 'copy dropbox link' and paste the public download link directly into the support ticket email. If you have any problems with dropbox try using filedropper.com.
