I need your help please urgenlty to install the knime nodes found here

I failed using the knime sdk

I can run it from knime sdk but whenever I export it as pluigin it gives error

These nodes are not released yet. You need to contact the authors about the current status.

they don't respond......strange that I have been using them in the past releases (maybe 4 years ago)
