Won't receive emails from Gmail account (pop3)?

I am trying to set up my gmail accounts. One of them works just fine, but the second only sends emails, it doesn’t receive any. It doesn’t give me any errors, and if I log into my gmail account the test emails are there. What do I do?

Send us your POP3 log. Go to Tools - Settings - Logging, check POP3 under the problematic account and restart eM Client. Then try to simulate the issue (Click send and Receive) and send us the log using the same logging settings window. Thank you.
