I think Poser uses the Internet Expolorer Interface/API, that's why you have to configure the Internet Explorer, whether or not you are using Google Chrome for Web browsing. So can you please check your IE version? You will need to work with Internet Explorer 7 up to 10.

Smith Micro: "INTERNET EXPLORER 11: Poser 8 and Poser Pro 2010 are not compatible with Internet Explorer 11 and may fail to start or fail to display the embedded library if you have Internet Explorer 11 installed. You can look into uninstalling Internet Explorer 11 and reinstalling an older version of Internet Explorer (versions 7-10 should work fine) to get the embedded library working again."

To go back to an older IE version isn't hard. Here you will find a good explanation on youtube (less than 3 minutes): https://www.youtube.com/watch?v=cUy5LKDdMTs
