Hi djaydino,
Thanks for your reply.
That's what I did. I removed the whole 'Hutong Games LLC' folder from the local asset store folder. Then I downloaded Playmaker in Package Manager and imported it.
I'm just looking for some way to double check if the version is correct. Just to be completely sure. Maybe there is some file (maybe one of the dlls?) in the Playmaker folders that can tell me if it's 2017.4+, 2018.3+, or 2019.3+ version.
Thank you.
