Yeah, when you deleted the old Pitch object, that deleted the tab. But the new Pitch object, the one from Max's Pitch Package, came with it's own tab. Now you just have to add that tab back to the Marketing app. That's the steps right after you installed the package back in 1b. Do those to get the tab into the app. Then you should be able to resume where you left off in 2a.
