Hi.
If you have a fresh project there should not be issues.
If you installed playmaker while there where some errors in the console the installation is not completed.
1st look if you have some red errors in your console windows, if so try to resolve those 1st.
Then look if you can see Playmaker in the top tool bar.
If not, then in the project window go to Assets/Playmaker/Editor/Install and double click Playmaker 1.9.0
This will continue the playmaker installation.
If you dont have a playmaker foler, then you need to reimport from the store.
Once installed correctly you should have Playmaker in the top toolbar.
Select Playmaker Editor to open the playmaker window.
Again, make sure there are no Red errors in the console else Playmaker (and other utility assets) will not be loaded.
