Claws-Mail: timeout on send and receive

I installed gpg4win-light-2.1.0-svn1407-colin.exe on my Windows 7 PC. I successfully converted/copied mailboxes from my Ubuntu PC that used an older version of Claws-Mail.

I am getting timeouts on send (SMTP) and receive (POP3). Unfortunately the log window only says contacting the server… and timeout. Is there any way to configure/increase the log level so that I can see more? I am using the same settings as on my Ubuntu PC; I do not think the ports are blocked; I need to see more of the diagnostics.

Thank you,
