After accidentally skipping a step, I used the back arrow to go back to the previous step and I started back doing the steps again but once I got to around step 14 I got a message that said 'duplicate' and it would not let me go any further, I believe I know why it said this because I had already done this step which makes sense.
Sorry you're stuck but there's almost always a pretty easy fix! Do NOT try to start all over again, eg. uninstall Max's Pitch Package, etc. That can make things worse.
