Absolutely start with Fundamentals 1 & 2 and remember [u]be patient[/u] ( most important ) .....go throught every minutes in the video and practice alot . Don't go to next lesson until you understand it 100% . I'm sure you will see alot " ah - ha " moment and understand the WHY of how a guitar is laid out, HOW notes related to one another, chords related to one another etc. in Fundamentals 1 and 2 . I am 47 too and I have the same problem like you last few months ago but now I understand alot about guitar . Good luck !
