I keep clicking Boss in Wrye Bash, and it'll show the little loading bar, but nothing happens afterwards. Nothing pops up in my browser. Now, I haven't used Boss or Wrye Bash for that matter in quite some time, and I updated it to 2.1.0, I think anyways. It keeps asking me to update it, and I've clicked yes several times. Any solutions?

This is just a hunch but check your firewall settings and if necessary turn it off termporarily to allow the BOSS server to connect to your computer. If that is the case... be sure to turn it back on after.

Actually, I fixed it. I had to update it via installer.
