Hello Inger,

from this error message I can see that the database is most likely corrupted.
You have to close eM Client before making any changes in the database location, proceeding without closed eM Client can cause the database corruption.
If your database is corrupted:

  1. If you made any backup of eM Client’s database in the past you can simply restore it and eM Client should start working without any problems.
  2. In case you have all your data saved on servers you can simply delete the database folder and start eM Client.It will create empty database where you can set your accounts again. All your data should be pushed to eM Client automatically then.
    You can find eM Client database here:C:\Users%Current User%\AppData\Roaming\eM Client

To locate AppData folder you need to view hidden folders in Windows: https://support.microsoft.com/en-us/h…
I will close the other thread you created because it refers to the same issue.

With regards,
