Error after switching Unity versions (or different reason?)

I am getting a strange error all of a sudden in my unity project (which uses kinect 2.0 sdk).

Some things have happened since I last pushed it to the unity cloud (i just pulled it in a fresh project). I switched the unity version and there was some git trial and error. I am not sure if I need to revert my unity version, or update the plugin I bought (can I do that separate from my new code which is now embedded in the project?).

Thanks for any help!
