Updated eM client today. Contacts gone, no email in folders except inbox but all e-mails from 2017 gone in this folder

Updated eM client today. All folders are still there but no contacts, no email in any of the folders except inbox and all e-mails from 2017 have gone in this folder

Same here Katherine, I reinstalled the older version but I would have expected eMClient staff to at least report on a fix. Disappointed.
