Hi,
- Have you just imported the unityPackage, or have you gone through the wizard? it's a 2 step process.
1: you import the package
-------------
2-A: if Unity has no error, you'll be presented with a wizard viy the "Welcome Screen"
and then you click on "Install PlayMaker" which triggers the update checker, move that window away, after you careful read the instructions to understand how actions may be affected.
then you have
where you finally can install PlayMaker 1.8.1, it will launch a package imported and this time roun you'll finally have PlayMaker 1.8.1 installed.
---------------
2-B If your project had errors in the Unity console when you did step 1, then the Welcome screen will not be fired. You need to first fix all errors in your project, OR you can manually import PlayMaker 1.8.1 by importing the package located in your assets:
Assets/PlayMaker/Editor/Install/Playmaker.18.1.unitypackage"
-------------
Let me know how this goes.
Another option is to simply delete the PlayMaker folder ( WARNING: check that you don't have templates and global variables, if you do you'll need to move them out of the PlayMaker folder first), and remove all PlayMaker.dll from the Plugins folder), and go through step 1 and 2B with manual import of the Playmaker.18.1.unitypackage.
Final note: ALWAYS backup before upgrading and verifying that the project is all good and running/publishing as expected.
Bye,
Jean
