I lost all of my emails afer upgrade for version 6.

I upgrade to 6.0.19705.0. I lost all the folders where was the archive of my emails and all of the emails archived. I only have the default folders.
How can I restore the folders and get back all my emails?

Hi,

we are very sorry to hear that. Do you have a backup of your database folder? If so, it will be easy to get your data back. Also please tell me what version you used before. Thank you.
Please contact my colleague Micek directly at micek@emclient.com so we can help you ASAP.
