Can't re-activate my UnityPro License, or even access the program at all.
I recently used a trial of UnityPro.
The trial ran out, and when I attempt to open unity I get this screen as expected.
When I click re-activate I get the following error:
The first time I signed up for a license I had to do so manually, however now I cannot even access the editor to fix the problem. I tried disabling my network, I tried disabling my firewall, I tried shutting off my router. I even attempted to re-download unity alltogether. No matter what I do I cannot get into the editor at all to attempt to download a license manually. I am using version 4.3.2, and cannot currently upgrade to a newer version for this project.
Once the trial runs out, that's it. You either need to buy a license (1500 USD) or download Unity Free.
I did purchase a license, the problem I'm having is that I can't get to the screen where I can renew it.

try the steps here: http://answers.unity3d.com/questions/358967/peer-certificate-cannot-be-authenticated-with-know.html
I tried disabling my network connection. It still won't allow me to open unity without first renewing my license. I tried re-installing it but it didn't matter at all.
