It looks like you have installed Ruby 2.0. When you get to the section on devise, your app most likely will break. I started w/ 2.0 on Windows 8, and could not pass the devise portion. Unfortunately, I had to start the course over with Ruby v 1.9.3. I have also read there are problems with newer versions of Ruby on Windows 8, especially 64-bit versions. You might want to uninstall 2.0, install 1.9.3, and try again. I hope that helps and good luck!

I should note: After installing 1.9.3 and starting over, I was able to complete the entire course. Also, do not run "gem update" at any time during the course.

Edit: Looks like there is a fix for the devise problem: https://teamtreehouse.com/forum/devise-updated-with-ruby-211-and-rails-403

try running gem install tzinfo-data and see if that fixes it

Thanks but unfortunately, no. Same error after installing the tzinfo-data gem

Going back to 1.9 did the trick. Thanks!
