Once I hit save, like how it says on the instructions, and go to pitches tab, I can't find my pitches tab?!

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!
So after you hit Save, doesn't it take you back, away from the page you are showing here, to the main page where you can see your Pitches tab and click on it? If not, please post a screencap showing what you are seeing (with no Pitches tab).
