I went to Live Chat and "Chris" told me it was my Security program, and to notify them to add Pirates. That didn't seem right, but I called my company anyway, and after 20 minutes on hold, I decided to figure it out myself. So, I tried to log in again, and when the 'Signature Expired' notice came up, instead of clicking 'Cancel', I clicked 'View Certificate'. The certificate popped up, and there was a choice to 'Run' it, so I clicked that, and Voila! New update loaded. But....it took FOREVER for it to load. It froze twice, and then when I actually got on 2 hours later, the ground was white in PR and Tortuga. But it went away.
