MCM Doesn't Show
If my MCM is not showing up for you when you start your game, my mod isn't at fault ... it is a SkyUI and/or game issue.
Here is talk about this problem from the creator of SkyUI:
"When starting SkyUI on a fresh save for the first time, you may have to save and reload (the game you just saved) to make all entries show up.
The detailed technical reason why this happens is that there is a script, which manages all the menus. After each game (re)load, this script asks in the room "hello, are there any new menus?". In rare occasions this request may be sent before a menu has been initialized. By rare I mean Papyrus decides when to initialize and it may be instant, or it may be after 5 seconds if there are other things going on at the moment. Anyway, if the menu is initialized too late, it may miss the first request. But the menu manager will give the menu another chance to register because it asks again after each subsequent reload.
I know it's not optimal, but I tried to fix it once by implementing a lock/wait mechanism in Papyrus and that went horribly wrong. A simple workaround for this issue is "load a game, if a menu is missing: quicksave, quickload".

You can try Woodclaw's suggestion:
".. open the console and type: setstage SKI_ConfigManagerInstance 1
Usually this forces the MCM to recognize the new menus."
