Email archive missing after reinstall

For one reason or another I had to reinstall eMClient a couple of weeks ago.

I tried searching recently for an email and noticed that old emails were not being shown, I checked under the local folders ‘tab’ and nothing was present!

Automatic archives are performed regularly, as a result I have a LARGE stash of old emails that I would hate to loose, how do I find and reinstate them into eMCLient?
