Open Windows task manager and make sure there are no eM Client processes running both in Apps and Background Processes.

Rename C:\Users_username_\AppData\Roaming\eM Client. You may have to show hidden items in Explorer to do that.

Open eM Client. If that works you can either setup your account again, or try the restore option.
