i can't find the "point xyz" component or the "curve" object components in drop down menu

hello

i just downloaded the latest grasshopper - and am following a tutorial that instructs making an object curve to input from a series of points. When using the drop down menu to search for components, I can neither find theĀ "Point xyz" (with inputs x,y,z & s) or the "curve" object (with inputs V, D & P). I have attached a link to the tutorial. https://www.youtube.com/watch?v=jfzud8r45TI&list=WLUPOvmPN6CvgG...

I've shown a screen grab from the tutorial of "Point xyz" on the drop down

When i type "XY", the drop down list appears, but there is no "point xyz" listed, only "construct point". That component does not have the same inputs...

A similar problem occurs in the next step of the tutorial when i'm trying to build a curve object. My drop down menu does not offer the same component as in the tutorial. The tutorial was published two years ago. Did the software change this much? how should i proceed?

Thanks!
