Although properly this should be in the mods section I am posting it here so as to increase the chances of getting help from a developer.

The title describes my situation exactly. I have created a simple custom campaign by editing the gc2campaign file for the Dark Avatar campaign and placed in a campaign folder for a mod I use for custom scenarios. When playing with or without the mod enabled, it does not show up to play anywhere. I am not at all computer savvy, I cannot intuit where to put this campaign so that I can play it. I am already very frustrated by the fact that I cannot play any scenarios in TOA - custom or otherwise - besides the normal sandbox mode, but up to this point at least DA has worked fine. I need help badly. The forum search is utterly useless as always and I cannot figure this out on my own.

Edit: Adding to my confusion (albeit relieving some of my frustration) I can get this same custom campaign to work in TOA! This means that TOA can run custom campaigns but not custom scenarios and DA can run custom scenarios but not custom campaigns. It's confusing and senseless.
