Just for the record. I hate to say it, but the Files option for this Group does correctly appear if I go back to Internet Explorer from old tried and true Firefox. So, if you do want me to upload something, I guess I can pull it off with the other browser.
As to the error log message, I have found that it is registered as Bug #696646, so I hope there will be some work-around or a soon-to-be- released fix.
