I am having a similar issue to what I encountered in 2a. It says I entered the data wrong again, but it appears to be correct. Do I have to un-delete something and edit that to fix it? Any tips to prevent this going forward? I have also granted access if necessary.
Sorry you're stuck but there's almost always a pretty easy fix! Do NOT try to start all over again, uninstall Max's Pitch Package, etc. That can make it worse. There's a 95% chance the same snag/fix is listed & answered in the Help FAQ. But if you can't find it there, post your problem here.
Make sure you post in the right category below & be sure to include a screencap showing the issue!
