Not able to restore archive

I’ve archived my mail because the mailserver was beeing moved. Directly after the moving I was unable to restore the mails and I unzipped the backup file. In the mean time eM Client made a new backup and removed the old one. Is there any way I can use the unzipped files to get the old mails back? I’m using eM Client version 8.2.1659

Your database should be stored at C:\Users\yourusername\AppData\Roaming\eM Client. You may have to enable hidden items in Windows Explorer to get there.

With eM Client closed, copy the unzipped backup folder to replace this eM Client folder, then start eM Client again.
