Pegasus Email 4.8

I've installed Pegasus Email 4.8 on my Windows 10 pc.  I use POP3, 995, SSL, and SMTP, 587, SSL.  I can send mail, but can't receive.  When  I try to receive mail, the program shows POP3: connecting to mail.comcast.net, but nothing happens.

(I use Windows Live Mail on the same pc, with the same settings, and it works fine.)

Any ideas?
