i used to be able to get to one that was GREAT, it had everything i needed to know... but i lost it when my old pc broke, are there any free programs anyone knows that are easy and good?
Use your ears, learn some scales and basic music theory, try to figure out basslines from hearing and try to avoid learning everything from tabs.

A program to teach you how to play? There is no magic-program, it all comes down to practice.
