Mayflash Gamecube adapter not working with DK64

[RagePlutia]

I don't get it. It worked with all games fine before I had to reinstall Windows 10. Now it works with games but with DK64 it has major problems, the axis and A B buttons work fine, Start works fine, but the C Buttons nor the D-Pad will work. I can't play and I've tried everything, from switching graphic plugins, to reconfiguring the button placement. I am using Glide 64 and N-Rage's direct input on Project 64 2.2.
