Hey, but even on version 10 this database is not readable , are there not enough files or what, why it cant read this database in version 10?
You carn’t manually open those hidden database files outside of the program if that’s what you have been trying to do.
If you install eM Client V10 and it won’t open and comes up with a database error, then you can try closing eM Client and manually repairing the database for Windows as per @Gary link.
Or if you have a Mac, close eM Client and then “open the Terminal app via either Launchpad or Utilities” on the Mac. Then Paste and run the following command.
/Applications/eM\ Client.app/Contents/MacOS/eM\ Client /dbrepair
If that still won’t open and you have a current active paid Pro or Personal or Business version, suggest to go to the VIP support page and login and lodge a support ticket.
