When creating a new project, all of the Editor Windows under the PlayMaker menu are greyed out. I've read through similar problems and have tried the following:
Window layouts have been reverted to factory settings.
Restarted Unity.
Rebooted computer.
Created a new project.
Thorough uninstall (deleting leftover folders and registry) and re-install of Unity.
Being a new project, there are no errors in the console.
This is with Unity 4.6.2f1 and PlayMaker 1.7.7.f6. I also tried the new Unity 4.6.3f1 with the same results.
Does anyone know how I might fix this? I can't use PlayMaker at all.
