Problems with Remote Client Update Version 3.8.4

When I installed Remote Client Update Version 3.8.4 I lost the ability to send mail. I logged out of ICloud and logged back in. No improvements. I closed out of my ISP account and logged back in. No Improvements. I am getting mail fine, I just can't send. Mac Connection Doctor says I have a green light on my ISP SMTP and my ISP POP and my iCloud IMAP.

Mac Book Pro Late 15 inch late 2008

OSX Version 10.9.5

2.53 GHZ Intel Core Duo

8 GB 1067 MHZ DDR3

I have four log files that I can't understand. Sample below. Will provide upon request.

What do I have to do so that I can send mail? Obviously this is highly frustrating.

Sincerely,
