When I start Unity 1. It opens the welcome screen. 2. I signed in to created an account 3. I created my account.
4. Now when I startup Unity it opens the Welcome window and when I fill out the forum (email and password) and click sign in, the message ‘Service not available, please try later.’ and I can not get pass this message. When I click on the face in the top right corner I can get into my account. But Unity does not start up. Can anyone tell what I am doing wrong. I am using Linux Mint 18 and everything installed alright.
