Retrocult/Raphnet Adapter wii guitar not working in fortnite

[jyunkerswave]

I have a raphnet adapter and a retrocult adapter. I followed the instructions on the retrocult website to use in fortnite festival. When I open fortnite festival, I get no pro mode and my guitar does not work. I tried using the raphnet adapter just to see if that would work but neither do. I disconnected both from FestivalInstrumentMapper and both work in clone hero. Please help.

EDIT: I got pro mode to pop up one time when using the retrocult adapter. When I started the song, it said "SWAP DEVICE" on the screen and I tried moving my mouse around and spamming fret buttons as the website said, but it still didn't work. I restarted my game and pro mode does not pop up anymore.
