I'm sorry you couldn't get it to work, can you confirm that you were able to download the zip file and unzipped it? After unzipping, you should just be able to double click on the "CreativeCore_Prototypes.exe" to run it, let me know if that works?
I did exactly that, I even created a new project of my own and tried to import it but nothing worked. I could have been an issue on my end, im not entirely sure
