Kuler has been dead for a while now and the other stuff appears to be post-CC 2014 only compatible with newer versions.
What is the difference between after effect cc 2014 and cc 2014.2
You can find the changelog by yourself if you are interested in the differences.
Currently the one plugin is dead (Kuler) and the other one needs at least CC2014.2 (Motion Bro). Pretty clear.
