Error while opening "Pioneer CDJXDJ ASIO"

Hi,

Rekordbox has been working fine until I just recently updated. 

I have tried everything on:

https://rekordbox.com/_app/files/img/Troubleshooting_001_E.pdf

I have reinstalled and rebooted multiple times and also turned Firewall off.

I am unable to see the driver when I look in: Open [Control Panel] → [Device Manager] → [Sound, video and game controllers]. 

I can link to my CDJ900s but songs won't load and it's super slow/laggy.

I also saw someone mention I should try install on Administrator user account (Windows 10), but sadly I am unable to access this. It shouldn't matter though because it has been working fine up until now.

Any ideas? 

Appreciate your help!
