@esmi: I apologize, but I am new on these forums, and I don't see how I've violated any rules as I've posted a follow-up to my own topic that I have created. I'm getting both error messages intermittently when I press Connect to WordPress.com which is why I posted the follow-up to help you, the developers, or anyone else track down the issue. More details about my hosting environment:
Hosting Provider: GoDaddy
Environment: Windows
IIS Version: 7.0
PHP Version: 5.3
So far the response from GoDaddy support is unsatisfactory. They suggested I downgrade to PHP version 5.2 or run the latest JetPack version... I have another WordPress installation running on another Windows hosting environment with JetPack 2.4 installed on top of PHP 5.3 that works fine.
