If your database was opened in 3.1.4.1 it will not be able to be opened in 3.1.3.0. The change from .0 to .1 on the end indicates a database schema change (for downloaded party hands). You will have to create a new database in 3.1.3.0. If you are already on 3.1.3.0 that can be done under the File menu. If you still have 3.1.4.1 installed you need to rename the DB, rollback, then create a new DB in the setup wizard that you can use while you have to temporarily rollback. Once our devs have time to review your/others logs and get a fix released you should then be able to update HM3 and manually import recent hands from the archive to get your previous database working again and updated with hands that you had played while rolled back.
You can use the following instructions to rollback to the previous build, but it will require creating a new database that you will have to use in that version as the schema changed when we added Party parsing support for downloaded hands.
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. If you can't see it, turn off the windows option that is hiding that directory.

Rollback to 3.1.3.0 from this link -
https://www.holdemmanager.com/downlo...ersion=3.1.3.0
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.
Then you can manually import your recent hands from the C:HM3Archive and/or C:\HMArchive folders until we can see what is happening and release a fix so that you can update HM3 again and then use the previous database again after manually importing hands you played while rolled back.
