On the first launch of Unity, it looped back and forth between a "no network connection" window and a sign-in window. I couldn't really interact with either because of the looping. I couldn't make this condition different no matter what I did, disabling the firewall (ESET), MalwareBytes, and even NVIDIA GeForce Experience (just because). I eventually figured out how to do a manual activation, but when I launch Unity it still says there's no network connection, even with the firewall off. But of course I wouldn't be able to post this if that was the case. Anyone have any other ideas to try? I Googled it but I'm just not seeing anything helpful. Windows 10, Unity 2017.2.0f3 (64-bit) Thanks.
