"Error intitializing communications with the LMS" in Captivate 8.0.1

After updating to 8.0.1.242 and publishing projects as SCORM 1.2 in html5, I get the error message "Error intitializing communications with the LMS" both in the LMS we use and in ScormCloud. This happens in IE 10.0.9200. I am pretty sure we have not had this message before. I had a colleague generate the same project for me using 8.00.145 and I get no error message. Any input on what causes this would be appreciated.
