Downloaded e-mails have disappeared

My POP3 e-mails in my inbox folders and the inbox folders have disappeared overnight on 12 January. The version is 7.1.31849.0 but I have done an update since the disappearance to see if that was the problem. I also get this error message which I have not had before. I also attach the log. Please help.

The IMAP error can probably be solved by removing the account, then adding it again.

The missing POP3 - did you delete or edit the account, or maybe something in the C:\Users\username\AppData\Roaming\eM Client folder?
