Error after latest update

Since the latest update to version 9.2.1735 (3d90379) I cannot send or receive emails using eMclient & Outlook account.
I can send and receive using Outlook OK.
How can I resolve this problem?

I am having the same issues with using eMclient with gmail account after latest update. Have checked all the account settings and they appear to be correct. Please advise as to how to resolve this problem.

It has put itself right today.
