I was provided the same steps, to delete all traces of the previous software and drivers, however since downgrading and using V2.10 worked, I really did not have the patience to waste any more time on this issue:)
Already did most of those steps during my troubleshooting, took me around 3 hours to sort it out. Most of the time was waste trying to get previous versions of the software.
Just in case this wasn’t clear. Version 2.11 does work, however it only does so when you first install it. The moment you shutdown and restart your PC, that’s it, it no longer works. Only fix is to uninstall and reinstall, and it will work again until you restart your machine.
