Searching emails

I have been using eM Client for a year with no issue. However, all of a sudden the search function won’t work. When I try to find an old email with a keyword such as the senders name or message topic nothing shows up. It started happening only a day or so ago. Please help!

If you click the down arrow in the search box, make sure that the search field is Subject, sender, recipients and body. If it is just Subject , it will not search for the sender/recipient’s name.
