Hello,
in the first place please download and install the latest version of eM Client (emclient.com/dist/v4.0.14479/setup.msi). If the problem persists, send us your POP log please. Go to: Tools - Settings - Logging, scroll to the problematic account, check POP3, try to simulate the issue and send us the log using the same window. Thank you.
