tweener engine

[jk82082]

I just started using this tweener engine and I am enjoying it, but I have a question about it. I google it to download the caurina files from the official site. I then ran across some demo files on the site and downloaded them, but they seemed to have a different version of the caurina files with them. I ran into problems with the color property with one set of the files, and one set had an extra folder called properties in it. Does anyone know what the right version is? Thanks.
