I am not sure if i can’t upgrade to Unity Pro trial or if i already did this in the past and as a result of this license has expired.
I am following all the steps to upgrade the license:
1)Generating properly a license according to my serial number(https://license.unity3d.com/)
2)Loading the new license(Help->Manage license ->Manual activation->Load license)
3)Activating the new license(Help->Manage license → Activate new license)
Using the same serial number. After clicking OK, a “Please wait” message appears
and nothing happens. The Unity version is still the free version. Nothing changes in Help->About Unity, The Profiler is not enabled etc…
Any ideas?
