I got this e-mail from Unity asking me to help testing the 5.4 beta version. I have downloaded the 5.4.0b2, installed it and started it. I've also allowed it to pass through my firewall and signed in. Now I am faced with the issue that it doesn't recognize my pro license. I get this dialog window when I try to open a newly created project: I have paid a one time fee for Unity and is therefore not a subscriber, don't know if that would be the issue. Any suggestions?
