4.5.9 is the latest version. All the tutorials on should apply. There are also older tutorials on youtube / vimeo.

The reason you have the error is because you have 2 input scripts for changeActionToStop. They are variations of the same routine and therefore will have some of the same labels in them. Get rid of one and it will work. There is no reason to have both.

It's because you have added duplicate input scripts... (the"ChangeActionToStop.asm" and "ChangeActionToStop_UnlessJumping.asm"... and the "ChangeActionToMoving.asm" and "ChangeActionToMoving_unlessJumping.asm").
If it's a Platformer/MetroVania project, I suggest to remove the "ChangeActionToStop.asm" and "ChangeActionToMoving.asm" scripts from the "Input Editor" and from the "Scripts > Input Scripts" (on the left pane of NESmaker).
And the compilation errors should go away.
