Here's your proof of purchase, since you deleted my post, since seller asked you too, since he banned me from discord (hilarious):
And here's original message:
I'm unaware how should I post proof regarding nVidia drivers deletion, but you guys can always try this software yourself and see if I was right, for all I care..
Seems to me, that seller, instead of addressing the software bugs, is choosing to silence the negative feedback.
It is all just my opinion, which does not have to be same as everyone else's..
