I've noticed that sometimes when you log in that it gives you the "You Successfully logged in" window, but it seems that you still are not logged in. This has happened to me to. The solution is to log in again.
This site is organized fairly simply. There's a lot of info here (about 2 years of study material) so spend a little time to get familiar with the interface.
If you are a beginner and want to learn the notes, rhythm etc, just go ahead and start with the 1st section and work your way through each section.
You can also just work on each section as needed. If you need help on chords, just work on the chords section etc.
You can jump around and find or search for what you need. If you are tired of learning notes, jump to one of the repertoire pieces that you can learn using tablature.
You have to enable pop ups, as a lesson will appear in a new pop up window!
You will need quicktime to view the video and hear the audio. Click on logo for free download:
