Thanks for your quick response,
I'm not sure if I understand correctly, but I don't think this solution will work for me. I tried and the same errors and blank space appeared.
I bought Playmaker directly from your website and I've received a mail sending me a link to the files.
I did not receive a new link, therefore I'm not sure if this version is the correct one that should be working with 2017.2
Beneath are some pictures that hopefully further explains this.
