[SOLVED] Gamecube Wii U adapter no longer working

[John Ghostly]

I'd managed to get the Wii U adapter working with dolphin after installing Zadig, however after installing drivers for the Xbox controller The Wii U adapter no longer seems to work with Dolphin.
I have tried reinstalling WUP-028 in Zadig, but I end up receiving  the error "Driver installation failed"

Any Ideas on what I should try next, or what I should do to fix this problem?

EDIT: resetting my PC seemed to work. No idea why.
