And I can't get it to work. I'm on windows 10 64 bit and using Ethereum Wallet 0.8.8. I've 8Gb of Ram and more than 200Gb free on hard disk.
I'm working on "real internet" and NOT on private network. I only want to mine something and try to deploy my contract and exchange something on test network.
