As you can see in the screenshot below I am not able to view the Pitch tab on the top. I was wondering why is problem was occurring. I was able to view it in Lab 1A but not in lab 1B.
Sorry you're stuck but there's almost always a pretty easy fix! Don't try to start all over again–not necessary! Don't start undoing stuff and don't uninstall Max's Pitch Package, etc.
There's a 95% chance the same snag/fix is listed & answered in the Help FAQ. Check that first but if you can't find it there, post your problem + a screencap in the proper category below & we'll post a solution back ASAP!
