First, make sure you are using the latest version in the Release History.

Next, close eM Client and open a Windows Command Prompt. Not a powershell, but a command prompt.

Paste in this command including the leading "

"C:\Program Files (x86)\eM Client\MailClient.exe" /dbrepair

When that is done, restart eM Client.

Great Gary, took some time but worked fine.
Thanks
