So I got a code from Amazon during the free code bonanza and registered it, then got a code from the place where I bought my 1070 two weeks ago. I've been holding on to the second code in order to sell it on ebay, but I see now that Nvidia has taken down the website?
Any chance it will come back up, or should I contact them?
It'll come back up, eventually. But they're holding off since you did the Amazon code thing.
