Sorry you are feeling discouraged. I'm no expert on BiAB but I don't find it any more complicated than my DAW which I'm no expert on either. I still make mistakes and run into things I don't know how to do in both.

In the ten years i've been using BIAB, I've found the friendly folks on the forum to be a huge help if something isn't working right when i'm stumped and can't figure something out. So I hope when you're feeling frustrated, you won't hesitate to take advantage of the help available here.
