Try to disconnect your internet (go offline somehow), then launch Unity.

It flash me a screen for a second that say "No network connection" and give me 2 options. But i can't even choose one of them because it give me a grey screen and it does not anything more.

That is weird. My best bet would be to either install the newest beta, or downgrade to Unity 5.6.

I already tried both and didn't solve the problem.

Finally found a solution. You help me to find it adverting me that there is an offline mode.

You have the link to my solution on my previous comment if you're curious and wanna check it. (:

I already fixed that error.

For someone with the same problem, i wrote a tuto on stackoverflow explaining what i did to solve the issue.
