I'm getting very frustrated. This is the third time I've tried to go through the "building a simple web application with Rails" series and, for the third time, it does not seem to work for me like it works on the videos. I don't know if it's that the videos are outdated, but it just doesn't work like shown in the video.

I think I've probably thrown more tantrums trying to learn this stuff than most of the 2 years out there. I swear this stuff is like a constant assault on my self esteem. But it's cool, challenging work, and so much fun. The frustrations will never go away because as you keep learning this stuff you'll keep doing more complicated and bad ass things on a different level. I wish someone had said this to me early on but work on getting really good at getting unstuck. Part of that means being able to handle the many many frustrations that lie ahead and sometimes it means closing the computer and going for a run.
I think you're right that course might be outdated. They should maybe put a flag of that if they don't already in the show notes.
Can you check your Gemfile and see what version of the rails gem you have?
After that, pull up one of the videos from that course and check what version of the rails gem they are using is. There are some big difference between rails gem 3.x.x and 4.x.x.
Are those versions different?
I also might recommend starting with this course http://teamtreehouse.com/library/build-a-todo-list-application-with-rails-4
Or, make sure you have the exact same version of everything in the video you're working on. But I would recommend starting with the todo list app above.

If you want to build treebook app, you need older version of Rails (3.2) and some of the gems OR use virtual machine dedicated for this project (Treehouse offers these) OR try to translate this into Rails 4.

Treehouse courses are just like books you buy off Amazon, the material is written against a particular version.
If you want to make things easy on yourself always use the same version of the software as is being demonstrated in a tutorial. If you are more adventurous, use the most current version and try and figure out how to translate it yourself.
