It wasn't a browser issue. This was the DESKTOP version. It turned out to be a strange Windows networking error. The rep wasn't able to launch either of his tools. My system had no problem on any other web site, but it seemed to block anything going to the Turbotax support site. We checked for the latest updates on windows and TT Desktop.. All up to date. I found an optional windows networking update, installed it, and everything started working. So can't figure out the cause, but did fix it eventually.
